I have the error below with Outlook. Does anyone else have this issue ?
[IMAP] Known Microsoft Exchange server error “User is authenticated but not connected.” has been encountered on IMAP connection. This issue is temporary and should be automatically resolved by the server. If not, please contact your mail provider.
Normally the automatic email wizard setup works fine and is probably server related as @Gary advised above from your error, but otherwise the below post may also help you from a user in the following thread who used an Outlook website generated app password for that error message.
