Good day
I have an Exchange 2010 SP3 hybrid environment with Azure DirSync. I have migrated all my mailboxes and public folders to Office 365. I have also decommissioned one of my Exchange 2010 servers and I have one last server which I would like to decommission so that I'm on the full Office 365 suite.
What are the steps to remove the last Exchange server while still making use of DirSync to keep my AD sync'ed? Should I upgrade the Exchange server to 2013? If so, can I use a trial edition for this purpose?
Any help would be greatly appreciated.
Regards
Bradley
