I am getting some strange error with one mailbox when moving it from exchange 2010 to office365.
It gives me error something like. MSEXCHANGEGUID IN MAILBOX PROPERTY IS MISSING.
If you need exact error. Let me know. But i think from this you will get an idea
I tried to make move from both way.
From office365 portal.. by selecting move mailbox to online
And also from exchange.by selecting remote move request
Any help will be really appreciate
