Hello all.
I have a happily migrated Exchange 2013 server to Office 365. It has been working fine for many months. I have left the server in place with DirSync in order to use the hybrid functionality. My question is what can I do with the existing on premises mailboxes now in order to save space? I can’t seem to find any answers to the question on how to just decommission/delete the old mailbox data left over. I want to reclaim all the space used up by the EDB’s on the servers now that everything is up in the cloud.
Thanks for any help on the subject.
