StefanKi&nbsp;I guess there is a bit more work, as you will need to update your MX and CName record for the autodiscover.Check this onehttps://www.easy365manager.com/remove-on-prem-exchange-from-hybrid-environment/and this is also goodhttps://docs.microsoft.com/en-us/exchange/decommission-on-premises-exchange&nbsp;

farismalaeb&nbsp;ThanksUpdate your MX and CName record for the autodiscover is already done.&nbsp;The migriation was not with hybrid exchange. I created not a hybrid exchange enviroment. Just use the migrate button in exchange online.&nbsp;

StefanKi&nbsp;I guess I wrote a reply, but then it disappears or I replied somewhere else to someone else :), AnywayIf this approach you used then it's OK, confirm your DNS settings, and remove the connectors.Shutdown your exchange server for some time and see what will happen, if all is fine, then you can continue with the uninstall process&nbsp;&nbsp;----------------------------------------------if my answer fulfill your needs, please don't forget to click on Best Response and give a like 🙂Thanks
