We have been migrating mailboxes from Ex2010SP1 to Office365 using the EMC, and it's generally been going well. However, several of the migration mailboxes failed, and I could remove the move request from the O365 forest without issues and the mailbox would become available for migrating again, but several of them do not. They have stayed with the green icon as though they should still be migrating, yet they have no move request left as I deleted the failed move requests. (I confirmed via Powershell). It has been several days for most of these ones, yet they still are not available to migrate again. Other mailboxes that have not yet migrated are still available and have the option to do a "New Remote Move Request" as normal.
Has anyone else encountered this or have any suggestions for a solution to make them available to migrate again?
