Hi there,
I have recently migrated all our on-premise Exchange 2007 user mailboxes to Exchange Online/Office 365 using a staged migration running DIRSYNC (Windows Azure Directory Services Directory Synchronization Tool). Now I would like to remove the old on-premise Exchange server but I am not sure if that would break things.
Also with Disync enabled you cannot manage some mailbox properties in Exchange Online, it needs to be done with AD, right? If that is the case is it a good idea to have Exchange 2010/2013 Management Tools installed to manage the mailboxes?
Thank you,
Pieter
