I have noticed the following event on Exchange 2010 servers after upgrading Exchange 2010 RTM to Exchange 2010 Service Pack 1:
Log Name: ApplicationSource: MSExchange ADAccessDate: 9/26/2010 9:12:29 AMEvent ID: 2937Task Category: ValidationLevel: WarningKeywords: ClassicUser: N/AComputer: EX1.companyabc.comDescription:Process w3wp.exe () (PID=1960). Object [CN=Jeff Guillet,CN=Users,DC=companyabc,DC=com]. Property [HomeMTA] is set to value [companyabc.com/Configuration/Deleted Objects/Microsoft MTADEL:0a05fe00-f8ce-4016-bba8-dce98cfe6b93], it is pointing to the Deleted Objects container in Active Directory. This property should be fixed as soon as possible.
The process in the event varies, but I’ve seen:
- ExSetupUI.exe (when installing Exchange)
- MSExchangeMailboxAssistants.exe (when moving a mailbox)
- powershell.exe (when a user launches the Exchange 2010 management tools)
- w3wp.exe (when the user accesses OWA)
The event in the example above is most commonly seen, and is caused when the user’s homeMTA attribute is pointing to a deleted object in AD. To fix this for a specific user, run the following command from the Exchange Management Shell (EMS) on the server:
Get-Mailbox jeff | Update-Recipient
Or for all user mailboxes use:
Get-Mailbox | Update-Recipient
To correct the arbitration mailboxes use:
Get-Mailbox -Arbitration | Update-Recipient
These commands will update the user’s homeMTA value to the correct value.
I’ve also seen this warning for the Edge Transport routing group property, as shown below.
