The question in my previous blog post was “Can we decommission our Exchange servers after moving to Office 365?” and the blunt answer was “No, you cannot decommission your last Exchange server on-premises”.

During the upgrade of the Mailbox servers users were presented with the dreaded “The Microsoft Exchange administrator has made a change that requires you quit and restart Outlook.” dialog box.
