Exchange 2010 Mailbox move error “Strings that includes ‘@’, where ‘@’ cannot be the last character”

When migrating a mailbox to Exchange 2010 i came across an issue, where every time i tried to move the specific mailbox i got the below error.

Property Expression “User name” isn’t valid. Valid values are : Strings that includes ‘@’, where ‘@’ cannot be the last character.

Resolution

 The username i was trying to move did not have an @ sign in his name so i didn’t see why this was failing, so this prompted me to look at the users account in AD.

I viewed the properties of the user account and then i checked the account tab, and i spotted there was no domain name specified in the user login name, which would explain why exchange was seeing it as “username@” so i added the domain entry in and then retried the move via exchange and it worked fine 🙂

Hope this helps.
