Hi,We've encountered a problem where the Submission queue appears to be corrupted and causes the transport service to keep restarting itself. There's about 2,000 messages in the queue, but we can't get to them as you can't export or manipulate that queue. I've not redirected mail via another Hub Transport role on a different server, but don't know what to do with the mail.que file that won't process.Any ideas on how to fix this would be helpful. I haven't been able to find the cause, but assume there's a dodgy message in there somewhere.Thanks,Ben

here is how you can clean the queue http://technet.microsoft.com/en-us/library/bb123535.aspxon exchange 2007.or Stop Exchange Transport Browse to the folder where mail.que is stored (By Default it will be c:\program files\Microsoft\Exchange Server\TransportRoles\data\Queue) Delete or move everything there Start the Exchange Transport Raj

Thanks for the link. I've been through those TechNet articles and it doesn't look like they'll work here: "You cannot remove a message from the Submission queue." The submission queue appears to be impossible to manipulate.

And ideally we'd like to recover the messages in that queue. There must be some way to get them out.

By exporting the information from the queue with get-message, I can see that it's now turned all the message that were in there in to NDRs. However, it's still not processing them.

Hi, I suggest you take the following steps: Backup Queue folder Stop Transport Service Ran eseutil /mh against mail.que on the production folder to verify if its a dirty shut down status. Ran eseutil /p on mail.que, to repair the database Remove all other file in Queue folder except repaired mail.que Started Transport Service Force the queue to connect and test the issue.
