We are using a toolkit to transfer our clients onsite exchange into Office 365 , there are about 125 mailboxes . There is one mailbox that isnt completely transfering. When we try to sync that particular mailbox to office 365 it shows lots of errors and Office 365 rejects about 2000+ items. The problematic mailbox is on an apple with Microsoft 2011 office. The whole environment is windows network.
In the past we had a EDB corruption on the exchange and this could be the root cause. We are wondering is there a way that we can clone the mailbox and totally upload to office 365 importing the errors too.
