Source Side Operation Failed - Exchange 2010 DAG

I came across this today. I have no idea why the database failed to replicate correctly, especially as it was a new database with no users on it. However fixing it was fairly trivial.

The issue:

Once I was back in the console I actually couldn't see the suspended and failed copy without having to restart EMC (a refresh would not work) however EMS did infact show it:

So via Powershell I simply ran the Resume-MailboxDatabaseCopy and this fixed the issue.

Testing via EMC I noticed once it was restarted I was able to see the failed and suspended database so could have performed it via the UI if I needed too.

Root cause analysis was not done as I was unable to replicate the issue. Hopefully this article will help any other Admins with the issue that may not be quite as quick at fixing it.

Take Care
