Migrating from Office 365 to on-premise Exchange 2010 server.
We are looking to move from our Office 365 Exchange services to an on-premise Exchange 2010 server. Are there tools or methods for doing this that does not involve manually exporting a PST file and then importing this file on the new server? We have over 50 users we need to migrate so manually exporting each PST would take a huge amount of time. What are my options for moving back to an on-premise server?
Then build your real server.
At that point you can then do a move mailbox on to the new server out of Office365.
Plenty of documentation on the co-existance.
