Exchange Deep Thoughts

Dynamic Distribution Groups

2008-11-04T09:22:00.000-08:00

So i'm sure everyone agrees that it is an annoyance that through EMC the only attribs that can be used for dynamic groups are company, state, department or the custom attributes.

Much has been written on using opath filters in PS to get around this limitation, but since using office location is so common i thought i'd just post on how to create a dynamic distribution list in exchange 2007 using the AD attribute Office Location

New-DynamicDistributionGroup "*ALL at OFFICENAME" -RecipientFilter {Office -eq 'OFFICENAME'}
Of course you can do a whole lot more with the recipient filter, for details, see here: http://msexchangeteam.com/archive/2007/01/10/432143.aspx

A few thoughts about SCR target activation

2008-08-28T10:17:00.001-07:00

I recently activated an SCR target as part of adding a mailbox server to remote office. I couldn't find much on the web about how long the activation would take, or what if any effect SCR activation would have on BES. All clients are outlook 2007, so i knew autodiscover would take care of the mailbox move. I used the activation procedure found here: http://technet.microsoft.com/en-us/library/bb738132(EXCHG.80).aspx

First, on the time to failover to SCR (or activate SCR target)

1. I used a target DB with the same log file prefix (E04 in my case) so i wouldn't have to mess with eseutil or worry about the DB being in a clean shutdown state (the mount-database operation would clear up a dirty shutdown with matching prefixes). I would suggest this if you have the ability to do so as it allows you to skip several potentially time consuming steps.

2. The resume-storagegroupcopy cmdlet took about 7 minutes to complete. There were 0 logs in the copy queue and 50 in the replay queue (kept with the defaults when setting up SCR).

3. I manually replicated AD after the move-storagegroup path, again after move-databasepath and again after move-mailbox, this might have been overkill, but with our site repl at 120 minutes, i didn't mind a little over kill. This added about 10 minutes to the process.

4. The move-mailbox -configuration only went extremely fast; 50 mailboxes in less than 5 seconds.

5. The mount-database was also extremely fast, but i would assume that is b/c it was in a clean shutdown state, it may take a little longer with a dirty db shutdown.

overall, the process took me less than 20 minutes of downtime, then add another 10 of bes downtime when i realized i had forgotten to give the BESadmin account the necessary permissions on the mailbox server.

Enumerate all members of a group

2008-07-01T08:10:00.000-07:00

this works for any type of group; thanks to Amit Tank from the technet forums for the syntax! Again the actual pipe key doesn't show up in blogger so I've replaced it with the word PIPE.

$grp = get-group “Group Name”
$grp.members PIPE fl Name

My 15 minutes!

2008-06-05T16:22:00.001-07:00

http://edge.technet.com/Media/Change-control-using-Sharepoint-2007-with-DPM/

Well, 9 minutes and 16 seconds anyway.

Some Handy powershell cmdlets with syntax (note the pipe doesn't show up in blogger, so i'll use the word PIPE)

2008-05-19T11:27:00.001-07:00

Setup Resource Mailboxes (like a new conf room).
1st, add create the new mailbox with EMC, then with EMS:

Add-MailboxPermission -AccessRights FullAccess -Identity ResourceMailbox -User Test1
Set-MailboxCalendarSettings -AutomateProcessing:AutoAccept

Add Mailbox Rights
Add-MailboxPermission "Mailbox" -User "Trusted User" -AccessRights FullAccess

Get Mailbox Sizes for all users
Get-MailboxStatistics PIPE fl totalitemsize, displayname

Set Rights for BesAdmin on a mailbox server (any time one is added)
Get-mailboxserver PIPE add-adpermission –user BESAdmin -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin

Get Mailbox Size/Location for 1 user
get-mailboxstatistics user.name PIPE fl

To get detailed information about the mailbox and what folders might be large, run this:
Get-mailboxfolderstatistics user.name

Force the GAL to update:
Get-globaladdresslist PIPE update-globaladdress list

Godaddy.com Subject Alternate Name certificate (SAN cert)

2008-05-06T14:47:00.000-07:00

I purchased the UCC cert for 5 domain names for $90 (they don't call it a SAN cert) and added the godaddy trusted root cert into the main certificate store, then with the SAN cert just from powershell :

import-exchangecertificate -path c:\owa.company.com.crt enable-exchangecertificate -services IIS, SMTP, POP, IMAP

the pipe won't show up on blogger but you need a pipe before the enable as you are passing the import command data along to the enable command.

Passed 70-238 with a 908

2008-04-30T17:44:00.000-07:00

This test was just weird. 70-236 and 70-237 were right on with the MS objectives, however this one was just all over the place. I obviously can't say much about it, but like any other test, if you have real world experience and know your stuff, you'll pass. At the time of this post, neither 237 nor 238 have books released so I just took the tests blind (but with 2nd shot) and passed easily from being in the trenches with exchange 07.

Passed 70-237 with a breeze

2008-04-18T16:38:00.000-07:00

That was a little too easy I think, I got a 921, again the exam objectives on the MS site are all covered, know your AD infrastructure or don't even try this one.

Passed 70-236 today, taking 237 friday

2008-04-15T14:00:00.001-07:00

Obviously I can't say much about it, but the exam objectives listed on MS's site were dead on. The test did make me wonder who really backs up the queue databases on their hub transport servers?

There is no book out for 237, so I'm taking blind (thank goodness for 2nd shot). Wish me luck.

Public Folders and Exchange 07

2008-04-08T09:06:00.001-07:00

So SP1 gave us some GUI management, but still no way to set permissions with the gui other than 'send as'. The 2 most common resolutions to this problem are 1. Leave PF's on Exchange 2003, and 2. Suck it up, and deal with it in powershell; here is how:

To modify the permissions of a top level folder to give the user "sally" editor rights and have this permission apply to all sub-folders, execute this command:

get-publicfolder -"\top level folder name" -recurse PIPE add-publicfolderclientpermission -accessrights "editor" -user "sally"

Use the pipe symbol, not the word, for some reason the symbol doesn't show up on blogger.

editing the default recipient policy

2008-03-04T12:49:00.000-08:00

For most of us, using the cmdlet

set-emailaddresspolicy "default policy" -includedrecipients allrecipients

will work fine, however some will get an error stating:

Unable to edit the specified E-mail address policy. E-mail address policies created with legacy versions of Exchange must be upgraded using the 'Set-EmailAddressPolicy' task, with the Exchange 2007 Recipient Filter specified.

This is generally because of a mailbox manager setting applied to your default policy, and exchange 2007 doesn't do mailbox manager. Remove the mailbox manager settings and re-run the command.

Creating Exchange 07 mailboxes with ADUC

2008-03-03T09:00:00.000-08:00

If you use active directory users and computers to mail enable a user account with an exchange 07 mailbox, it'll probably work and seem fine in outlook until the user tries to hit OWA. Then they'll get the error below. Also, EMC will list their mailbox as 'legacy mailbox'. To resolve, execute this cmdlet: Set-Mailbox username -ApplyMandatoryProperties

Exchange 2007 SP1 rollup 1

2008-03-01T08:08:00.000-08:00

Its got a lot fixes listed here: http://support.microsoft.com/?kbid=945684

All went fine for me in lab testing and in production rollout, however it did not start any of the exchange services upon completition, nor did it start IIS on the CAS server or ask for a reboot, so be prepared to either reboot or manually start all services.

Exchange 2007 leap year bug

2008-02-29T12:33:00.000-08:00

February 29th; what a day. I found that I could not create new users and isolated the problem to the date (it worked if you changed the system time to March 1st and stopped the windows time service). This is from MS PSS...all i can say is wow...its like y2k but stuff actually broke :-)

John,

You are absolutely right.

Symptoms of this include not being able to create mailboxes or create public stores or update email policy and results in an error “The Exchange server address list service failed to respond. This could be because of an address list or email address policy configuration error”. we found this to be a Leap Year bug and if we reset the date to either 28th Feb or 1st March it works.

We strongly recommend not to change the system time to work around the issue as this may cause undesirable results

I shall update as soon as we have some kind of solution to this.

Custom DSNs on Exchange 2007

2008-02-28T11:25:00.000-08:00

Tired of end users calling asking what an NDR means when its relatively clearly stated in the message body? The cmdlets set-systemmessage and new-systemmessage will allow you to customize them so they are even more clear, although somehow I think users will still call :-)

This example sets DSN text for an external 'unkown mailbox" 5.0.0 fail.

[PS] C:\>New-SystemMessage -DsnCode 5.0.0 -internal $false -Text "The intended recipient was not found. Please check the spelling and e-mail address of the recipient." -Language en

All you have to do is change the DSN code and the boolean for -internal to manipulate all the DSN's you want.

Generic Exchange 2007 Deployment Thoughts

2008-02-26T08:46:00.000-08:00

I was recently asked to review a 2007 deployment plan, and the high-level feedback I had was so darn standard, I figured I'd post it. The deployment was 2 CCR clusters, 4hub transports, 4 CAS, 1 Edge and 1 SCR target. The CAS and HUB servers were to run on VMWare. There was also a 3rd party SMTP gateway.

I would definitely recommend SCR, but write and test your failover powershell scripts/commands before you need to use them. As you also probably already know, virtualized exchange servers are not supported by Microsoft, but that does not mean it can’t work. Remember with CCR and SCR DB paths have to be IDENTICAL, so remember to use mount points, not drive letters. Also, don’t use the same DB/SG names on your separate CCR clusters if they are going to target back to a single SCR box (the file paths then become identical). Have a look at pfmigrate.wsf to help with public folders if you need it.

Another question to ask is, do you really need edge if you have a 3rd party SMTP gateway. If you have something like postini or frontbridge, you might be fine with routing inbound mail right to a hub transport server from the SMTP gateway.

For your cas/hub, you can run them both on the same machine as long as you don’t plan on using NLB, so you may not need vmware if that works for you.

My favorite site is msexchangeteam.com, but again, I’m sure you’ve seen it. If not, read up on their info on CAS certificates, very different requirements on 2007 than 2003 FE servers.

Exchange SP1: setup previously failed while performing the action Install. You cannot resume setup by performing the action "BuildToBuildUpgrade".

2008-01-16T14:02:00.000-08:00

If you are upgrading a CCR environment to Exchange 2007 SP1 from Exchange 2007 RTM and you attempt the setup.com /upgradecms and it fails, it'll keep failing with the error:

Setup previously failed while performing the action "Install". You cannot resume setup by performing the action "BuildToBuildUpgrade".

To clear this, you'll need to go into the registry and delete the watermark and/or action:install key located here:
HKLM\SOFTWARE\Microsoft\Exchange\v8.0\ClusteredMailboxServer

BES and Exchange 2007 transition

2008-01-08T12:18:00.001-08:00

Before moving any Blackberry Enterprise Server users from 2000 or 2003 over to a 2007 mailbox server make sure BESAdmin is exchange view only admin, then run this

Get-mailboxserver add-adpermission –user BESAdmin -accessrights GenericRead, GenericWrite -extendedrights Send-As, Receive-As, ms-Exch-Store-Admin

(for some reason the pipe doesn't show up after get-mailboxserver on blogger, but you'll need the pipe)

Once successful you can start moving Blackberry users as well as the BESadmin account to 07.

After moving the BESAdmin account you'll need to use the Blackberry server admin tool to point the MAPI profile to Exchange 07 as well as download and install the latest MAPI .dll files. The file info is documented here:
http://www.blackberry.com/btsc/search.do?cmd=displayKC&docType=kc&externalId=KB12697&sliceId=SAL_Public&dialogID=41824370&stateId=0%200%2041820640

Creating SG's/DB's in Exchange 2007

2008-01-08T10:45:00.000-08:00

Because of the path match requirements of CCR and SCR, most paths will not be to the default location. It is much easier to create the SG's and DB's with powershell and specify the path's then to use the GUI (too many clicks). I keep the following in a notepad doc and use find and replace for "executive 2gb" any time i want to create a new SG/DB.

New-StorageGroup -Name "Executive 2GB" -server "mailbox01"-SystemFolderPath "E:\databases\Executive 2GB" -LogFolderPath "E:\logfiles\Executive 2GB"

new-mailboxdatabase -StorageGroup 'mailbox01\Executive 2GB' -Name 'Executive 2GB' -EdbFilePath 'E:\databases\Executive 2GB\Executive 2GB.edb'

Mount-database "Executive 2GB"

OT: Slaves to the Robots Part II

2008-01-04T13:08:00.000-08:00

I would like our future Robot overlords to know that i've worked very hard to further technology and i would like a top-notch slave position or a quick and painless death.

OT: Slaves to the Robots

2008-01-04T13:06:00.000-08:00

My 2 year old is afraid of any non-living thing that moves. E.G. tickle-me-elmo. I think this is because he somehow knows he is part of the generation that will have to fight down the robots once they become self aware (to which Elmo is very close). If they can't beat the Elmo-led armies of robots, then the terminator movies become a reality...damn.

HTTP to HTTPS OWA redirect on Exchange 07

2008-01-03T08:17:00.002-08:00

With Exchang 07 SP1 having such a lovely and full featured OWA client, our users are using it more regularly, and complaining about having to type in the HTTPS:// for ssl.

To redirect, i set the 404.3 custom error (under custom errors, default website) and pointed it to an HTML file that re-directs. Note that with your users in 03 and 07 you'll want the redirect to go the /exchange directory, 07 only, use the /owa directory.

I'll put an image up with the HTML code.

Testing mail server via telnet

2007-12-18T09:45:00.000-08:00

I get asked for the steps alot so here you go; specific to Exchange/Windows SMTP (some mail servers have slightly different steps)

1.Telnet exchangeserver.domain.local 25
This will connect to your mail server on port 25
2. Type "EHLO" to open the session
3. type "MAIL FROM: yourname@somedomain.com
4. type "RCPT TO: this is the domain hosted by exchange to which you want to test relay.
5. type "DATA"
6. Type your message
7. Then terminate the message with enter . enter
8. Type "QUIT"

OT: SC DPM 2007

2007-12-11T08:25:00.000-08:00

First of all I really like DPM and found it very easy to setup if you can find the right DOCS (don't read the help file, use technet and search the internet). Also, most of the errors I encountered were resolved via newsgroups, blogs etc so it can be a little trying. I'm currently using it to backup Exchange 07 CCR, MOSS 2007, SQL 2000, SQL 2005 and domain controllers. Exchange 07, DC's and SQL 2000 were very easy. SQL 2005 required SP2 and sharepoint took some other steps as well. This is a great doc to get started: http://technet.microsoft.com/en-us/library/bb808827.aspx

One thing I did not find on the internet was a sharepoint problem I was having. I was getting an error stating "this windows sharepoint services farm cannot be protected......". It turns out you cannot backup the SP databases separately from the farm, so I removed the SP db's from the DPM protection group and SP is backing up just fine; now off to test the restore.

Forefront for Exchange re-install for SP1

2007-12-11T08:22:00.000-08:00

So the only way I could get exchange 2007 sp1 to install was to uninstall forefront, then re-install it after the sp1 install. This was fine in the lab, but i was very worried about doing this in production because of the customizations I had performed and 30 days of messages in quarantine. It turns out, all custom lists, customizations and quarantines are preserved even with a full uninstall then re-install. Way to go Microsoft!

SP1 and ActiveSync

2007-12-07T09:17:00.001-08:00

Make sure you've got an activesync policy defined and applied to your users that have windows mobile devices prior to installing SP1 otherwise they'll get the new 'default' policy which has been shown to break sync is some WM5 devices.

SP1 install woes part II

2007-12-05T14:14:00.001-08:00

Uninstalling forefront for exchange, then sp1, then re-installing FF worked, but i'll have to find some other way to work it when i roll production as i've got to many customizations in my production forefront.

Also, i've just started playing with the public folder management GUI, which appears to only let you manipulate the send as permission. I'm guessing MS is expecting us to use outlook or powershell for public folder client permissions (or I just missed an option); a little disappointing.

Well I'll be banging away at SP1 for the next few weeks and post what else I find.

SP1 install woes with forefront

2007-12-05T12:06:00.000-08:00

On a test exchange server i've upgraded to the latest version of forefront (at least latest available through MVLS 10.0.0.556), and the pre-req check of SP1 doesn't like it at all. Ive followed MS KB 929080, but to no avail. Still getting this:

Error:Setup cannot continue with the upgrade because Forefront Security for Exchange Server 10.0 was detected. Forefront Security for Exchange Server 10.0 needs to be upgraded to a compatible version of Forefront Security for Exchange Server first and its services need to be disabled to upgrade Exchange Server 2007.Recommended Action: http://go.microsoft.com/fwlink/?linkid=30939&l=en&v=ExBPA.3&id=6dfac22b-581a-4e10-938b-5f2498ead01d

I'm thinking i'll uninstall FF on the test box, install SP1 then attempt to reinstall forefront and re-post my findings.

Complete List of Exchange Powershell Cmdlets

2007-11-27T12:37:00.000-08:00

I'm often asked "Hey Knightly, how dow you always know about a cmdlet i've not heard of or seen?"...well its easy. They are all listed here, its tedious, but worth spending a couple hours to at least get the high level view of all the cmdlets.

http://technet.microsoft.com/en-us/library/bb123703.aspx

POP and IMAP on Exchange 07

2007-11-14T13:44:00.000-08:00

I get asked this a lot. "I enabled the POP and IMAP services on my CAS server, but POP and IMAP don't work, what's wrong?"

Well, nothing is wrong there are just a few more steps. 1st, you may need to configure your POP/IMAP configuration settings. Mainly most people have to change the authentication type using the command set-popsettings or set-imapsettings ( http://technet.microsoft.com/en-us/library/aa997154.aspx for set-popsettings...switches are the same for pop-imapsettings)

Also, you have to enable pop or imap for the user mailbox using the set-casmailbox cmdlet. Something like set-casmailbox -identity "new pop user" -popenabled $true . Or, you can get the syntax for that here: http://technet.microsoft.com/en-us/library/bb125264.aspx

Happy popping and imaping :-)

Installing Certs on your CAS server

2007-11-13T15:24:00.000-08:00

If you can, install the certs before you install the CAS role. This way exchange can just pick up and use the pre-installed cert/certs instead of creating self-signed certs which you'll have to go change later to keep owa/activesync/outlook from kicking errors.

4 Great Reasons to License the Enterprise CAL for Exchange 07

2007-11-13T13:35:00.000-08:00

1. Exchange Hosted Services. I implemented EHS in August of 07 and since then on average about 90% of my incoming mail is stopped by EHS thereby saving my proccessing time and power of my edge servers. Not to mention an avg of 400mb/day of internet traffic.

2. Forefront Security for Exchange: So i've got EHS scanning with 3 engine types and Forefront scanning with three different engine types. I sleep well at night. Forefront has also been great for attachement blocking and quarantine.

3. Unified Messaging. Gotta get rid of audix ASAP. Can't wait to have voicemail to email implemented. I'm still waiting on our S8700 SIP gateway to start working though :-)

4. Per-User/Per-Distribution List Journaling: The snoops in HR love this feature.

A handy site for recovering deleted items

2007-11-13T13:13:00.001-08:00

I, for one, can never remember how to pull PF info from the dumpster. Handy site:

ATT Tilt and WM6

2007-11-13T11:29:00.000-08:00

Wahuu! Wild Card certificate support in mobile 6 and its working great. I gotta say after 3 days I love the tilt. The built in GPS works well with google maps or there is a turn by turn application you can purchase for 10 bux a month. Now if only i could load my favorite golf courses into it.....

Connections days 2 and 3

2007-11-13T11:27:00.001-08:00

I just don't know how to pick the right classes to attend I guess. Overall, pretty dissapointed. The Exchange 07 stuff was all pretty 100-200 level while the Server 08 stuff just wasn't impressive. Well, better luck next year.

Connections day 1

2007-11-06T19:37:00.000-08:00

Not as good as last year so far, but picking up usefull info here and there. I think the next 2 days of sessions will be a lot better. I'm very excited for server 2008 terminal services and I did learn some helpful stuff with powershell scripting. I'll post again as I write some nifty scripts.

Exchange Connections

2007-10-30T10:32:00.001-07:00

Going to Exchange Connections conference next week. I'm really excited, and can't decide which sessions to attend between windows, exchange and sharepoint. Not to mention some vegas booze sounds like a nice break from the office. Check back and I'll post the cool stuff I learn.

ESMTP and PIX firewalls

2007-10-29T09:32:00.000-07:00

If you have a PIX firewall be sure to disable SMTP packet inspection or you'll see some serious mail delays/failures with certain ISPs. For more info, see Cisco's article here:

http://www.cisco.com/warp/public/110/mailserver.html

Delayed Fan-Out Routing.

2007-10-22T16:27:00.000-07:00

A previous post called 'a wierd one' may be solved with the info below, although i'm not entirely sure....the text below comes from a microsoft online course.

A message flow is disrupted if no Hub Transport server is available in the destination site. In such a situation, the message is routed to the closest Hub Transport server along the most optimal route. This is referred to as Queuing Messages at the Point of Failure.
The closest Hub Transport server then delivers the message when a Hub Transport server in the destination site becomes available. If a message has to be delivered to recipients at multiple sites, a copy of the message is delivered directly to the recipients at each site.
However, if destination Hub Transport servers are not available, then the source Hub Transport server delays making copies of the message for each recipient and sends a single message that is queued for delivery at the Hub Transport server that is closest to the destination sites.
When the destination sites become available, the queued message is sent to each site with a recipient. This is referred to as Delayed Fan-Out Routing.

Mailbox move fails if user password is expired

2007-10-18T10:58:00.000-07:00

So I attempted moving a user mailbox back from 2003 to 2007 and it kept failing. Turns out, the user’s password was expired so exchange couldn’t open the source mailbox. I wonder if there will be a fix out for that. The same behavior also occurs when the user is set to ‘change password at next logon’

Some Deep thoughts (a funny one I hope; jack handy style)

2007-10-18T10:08:00.000-07:00

Sometimes I wonder if Exchange appreciates all the work i give it, or is it like that alchoholic uncle that makes you mow the lawn then do the truffle shuffle and only gives you a beer that you don't like anyway because your 10 :-)

A weird one

2007-10-18T10:04:00.000-07:00

I'm currently running mixed Exchange 2003/2007 environment. I have all my DL's set to expand on on the 2007 hub tranport servers. During an Exchange 03 cluster failover, I sent an email to a DL that contained 15 users, all but 1 on Exchange 03. The message was not delivered until the 03 failover had completed.

Expected behaviour would have been that the message was delivered to the 2007 users and put in the RG connector queue for the 2003 user. I'll repost when i find out what the root cause is, assuming I can re-create.

I thought i'd just start off by saying hello and thanks for stopping by. I'm an email admin for a medium sized company and I thought i'd start blogging about the exchange stuff i deal with.
