The System Attendant mailbox on one of our Exchange 2007 mailbox servers (running in a Single Copy Cluster on Windows Server 2003) appears with a StorageLimitStatus of "MailboxDisabled" when I issue the command "Get-MailboxStatistics -Server mailboxserver | where {$_.StorageLimitStatus -eq "MailboxDisabled"}. While we're not seeing any obvious problems from our the perspective of our end users, this doesn't seem like a desirable condition long-term - and it looks like this condition is causing some alerts to be generated by our recently installed SCOM implementation. Having had to do this for a PSS case a while back (SRZ070820000310), I think I know the steps involved with moving the SA mailbox from one database to another so that it gets re-created - and cleared out/re-enabled in the process. However, I can't come up with the exact notes on it and searching only produces steps for Exchange 2003 so I'm posting this and asking for confirmation of the process for Exchange 2007. Note that I do not need or want to remove the mailbox database where the SA mailbox currently resides - I just want to move the SA mailbox to another location. Should the process below do the trick?Thanks. *Proposed* Process to Manually Move the System Attendant Mailbox to another store in Exchange 2007 1) Open adsiedit.msc2) Connect to the configuration context (Question: Does it matter what DC I connect to?)3) Navigate to Configuration > Services > Microsoft Exchange > Organization Name > Administrative Groups > Exchange 2007 Administrative Group > Servers > Server Name > Microsoft System Attendant4) Right click on the "Microsoft System Attendant" object and choose properties5) Choose "HomeMDB" and click edit6) Change the CN of the mailbox database to the one you wish to move the System Attendant onto.
