As you have noticed I am currently involved with turning up an Exchange 2010 server and migrating over. This doesn’t happen without learning some new tricks and getting to understand the new kid on the block. This is where New Local Move Request and I became friends.
I was unable to move a mailbox account that I had previously moved. It wasn’t long until I discovered that if there is an existing Move Request (pending, in progress, failed or completed) you will not see the “New Local Move Request”
The solution to this is very simple, so much so that you wouldn’t think of it until you ran into the same issue. Just find your way to ‘Move Request’ located under Recipient Configuration and you will have the option that reads ‘Clear Move Request’.
Move requests should be enabled again and you, are good to go.
