Log Name: Application Source: MSExchange Mailbox Replication Date: 26-9-2017 11:43:14 Event ID: 1121 Task Category: Request Level: Error Keywords: Classic User: N/A Computer: xxx.domain.local Description: The Microsoft Exchange Mailbox Replication service was unable to process a request due to an unexpected error. Request GUID: '4c037387-462c-446f-855d-1a4a9f4769bc' Database GUID: 'f76ac2d8-bf20-4646-88a1-5f9161f5f312' Error: Database 'f5c17f94-0b61-472e-9908-048b145e740c' doesn't exist.. |
Check if there are any open mailbox move requests, export requests, import requests of migration batches. If there are any open requests remove or complete these if there are no open requests you can fix the error manually using the following cmdlet:
|
1 |
Remove-MoveRequest -MoveRequestQueue "f76ac2d8-bf20-4646-88a1-5f9161f5f312" -MailboxGuid "4c037387-462c-446f-855d-1a4a9f4769bc" |
Where the -MoveRequestQueue is the Database GUID and the -MailboxGuid is the Request GUID from the event message.
The event errors should stop immediately. However you might notice that you are getting the error from multiple mailboxes (Different Request GUID id’s in event message). And you should therefore repeat this for each mailbox error.
