Hello,
i'm kind of stuck after migrate all of my mailboxes to office 365 about what to do with my on premise Exchange 2013.
now i have the following situation :
All my mailbox have been migrated from Exchange 2013 to exchange online, my AD is Dyrsinced and all flows are going through office365.
My on premise server is turned off since about a month and everything is going well.
i don't want to keep my on premise Exchange Server like is recommended by microsoft since i can manage what i want with AD Attributes and Powershell.
so can i uninstall the on-prem exch without worries ? since this will delete some exchange attributes on my users, how my office365 mailboxes will react? what is the best thing to do?
thanks by advance for your help !
