Move existing student mailboxes to Office 365
So what are the methods, we have a hybrid solution 600 Staff accounts on Exchange 2010 SP3 15,000 student mailboxes are going to be moved to the cloud.
At the moment we use DirSync to upload and password Sync.
We want only to be able to see the migrated students within the Office 365 section in the Exchange EMC, currently when we migrate we see them in the On-Premises Recipient Mailbox Section as well as the Office 365 Recipient section.
We only want to be able to see students in the Office 365 mailbox area so we can keep Students in a different section to staff.
Is there any way this can be achieved, is there another way to migrate the students over (15,000 of them) , like just the actual data as if they were never on our On-Premise Exchange server?
