EventID: 1006 Source: MSExchange Mailbox Replication

Question

Hi All,
On my Exchange 2010 i see the following Events in the Application Log.
The Mailbox Replication service was unable to process mailbox move requests in a mailbox database.
Database: MDB01
Error: Couldn't find system mailbox 'SystemMailbox{e0e13cb6-bd1c-4a67-b483-3fe8db9d3631}' in Active Directory.
But when i look at the Arbitration Mailboxes it's there.
[PS] C:\Windows\system32>Get-Mailbox -Arbitration | fl Name
Name : FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042
Name : SystemMailbox{A89BCF10-3F08-41C2-AC86-68E35C08D972}
Name : SystemMailbox{e0e13cb6-bd1c-4a67-b483-3fe8db9d3631}
Any ideas out there?
Regards Andres

Hi Andres,
The arbitration mailboxes in your product environment are not created by a correct way. I suggest you delete all of them and recreate them.
1. Delete those AD accounts.
2. Run Setup.com /PrepareAD. The arbitration accounts will be recreated after this step.
3. Enable those mailboxes with the following commands.
-   Enable-Mailbox –Arbitration –Identity “SystemMailbox{1f05a927-…}”
-   Enable-Mailbox –Arbitration –Identity “SystemMailbox{e0dc1c29-…}”
-   Set-mailbox –Arbitration –Identity “SystemMailbox{e0dc1c29-…}” -DisplayName “Microsoft Exchange”
Then please test the issue again. Thanks,
Elvis
