Just wanted to confirm on the behavior, i was trying to move mailbox from exchange 2013 to exchange 2019. Mailbox which successfully move was disconnected and require outlook restart to get it back connected.
However I don't see this happened for moving mailbox from exchange 2016 to 2019.
I also noticed this in outlook for the 1st time moving mailbox from 2013 to 2019. Its not showing anymore after moving from 2019 back to 2013 but outlook stay disconnected until restarted.
"The Microsoft Exchange administrator has made a change that requires you quit and restart Outlook"
