We have an onsite Hybrid 2010 Exchange server. All our mailboxes have now been moved over to Office 365. We are using DirSync to Sync our users and Passwords. I fully understand that I will need to use ADSI Edit to modify mail attributes if I decommission the onsite server. I also know the Non-Recommended/Recommende
d decommissioning method from MS from the link below.
I want to know your experience doing this decommission? Any problem with the mailboxes at the cloud after remove the Hybrid configuration and the exchange uninstall?
