Hello,

when creating an IMAP account (OnPrem Exchange 2019) the message “LOGIN failed.” without SSL the message “Command received in Invalid state.” always appears. I have already changed the password length, unfortunately without success.

The error message directly comes from your exchange server and can mean anything in authentication scope. It fails.

Ensure you’re using the correct credentials and that your IMAP service actually is running (cleanly). Exchange’s IMAP service loves to die.
