Hi There,
We have just migrated all of our users/shared mailboxes over to our new exchange 2013 box, from exchange 2010. But have noticed 4 mailboxes that appear as a Legacy Mailbox which appear in the exchange console but has no mailbox nor are they attached to a mailbox database. So cannot migrate them to the new servers. We know they are old accounts but the worrying thing is one of the accounts looks like its the Administrator account
Any suggestions on what to do here?
Regards
Ravinder
