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

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)

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.
