Hello, I've succesfully migrated from a single Exchange 2010 STD to a single Exchange 2013 STD.

The old Exchange 2010 was uninstalled and correctly removed.

However, my Exchange 2013 keeps logging some errors (Error 1121) in the application log:

The Microsoft Exchange Mailbox Replication service was unable to process a request due to an unexpected error.
Request GUID: '94ce118c-7f93-413e-aa48-5add05cce5bb'
Database GUID: 'cd830b2f-6233-4d73-aaee-8f4e8a164403'
Error: Database '88e47091-b918-409d-820c-c3e9bc23168f' doesn't exist.

I think that these messages are somehow related to some failed move requests during the mailboxes migration.

Nevertheless, a get-moverequest can't find any pending or failed move request.

A get-moverequest '94ce118c-7f93-413e-aa48-5add05cce5bb' gives me as result 'Couldn't find a move request that corresponds to the specified identity '94ce118c-7f93-413e-aa48-5add05cce5bb' '

How can I find and remove these failed requests?

Hi,

I recommend you try the following methods to troubleshoot the issue:

1.Please run the following command and check the result:

Get-MoveRequestStatistics -MoveRequestQueue 'cd830b2f-6233-4d73-aaee-8f4e8a164403' -MailboxGuid '94ce118c-7f93-413e-aa48-5add05cce5bb' |fl

2.Please restart the MSExchangeIS services and check the result.

Hope this helps!

Thanks.

Thanks for your answer.

Here's the output:

Hi,

How about run the following commnd?

Remove-MoveRequest -MoveRequestQueue 'cd830b2f-6233-4d73-aaee-8f4e8a164403' -MailboxGuid '94ce118c-7f93-413e-aa48-5add05cce5bb' 

Thanks.

I have this same request, but the errors keep generating. 

IIS Restart - no effect

Server restart - no effect

I can purge requests, but new ones are simply generated.

To make this more fun.  

Error

The Microsoft Exchange Mailbox Replication service was unable to process a request due to an unexpected error.
Request GUID: '91e57c02-759b-4d8f-8f20-7122fac0ee84'

Removal successful, but new ones simply generate.  What is generating them?
