Hello Everyone,
I have Exchange 2013 and tried to realice a cutover migration to Office 365, during the process some (350/700) mailboxes failed because the account that I did used did not have mailbox full Access permissions, also the system reach the max of retries (600/600). I alredy added the permissions, so What I have to do, to re-synchronize failed mailboxes without impact the mailboxes synchronized successfully? I think that:
Don't delete the actual batch, and create a new Batch and leave both batches synchronizing at same time.
is it Correct?
Best Regards
