Hi All,
I'm trying to transfer mailboxes from a Small Business Server 2011 with Exchange 2010, to a 2012 R2 server with Exchange 2013. These mailboxes already have a move-request associated with them, so upon trying to remove them with the "Remove-MoveRequest -Identity "User@Domain.com"" I get the error "Couldn't find system mailbox 'e257419b-0971-4691-b91f-b05423bf3ab2' in Active Directory.
I've heard that you can restore system mailboxes by running .\setup PrepareAD which worked perfectly fine with other mailboxes, but I'm unable to recover this one. I literally just need to recover this mailbox so I can remove these move requests and get these mailboxes moved over onto a healthy server.
Does anybody know the best way of going about getting this back? I could do an AD Restore of the Small Business Server but I would rather not do that if I have to...
