I think this would indicate that our Dovecot IMAP supports TLSv1.2 and should work with the Outlook updates. Am I missing something?
FWIW, I applied [Janno Sannik's patch](https://www.mail-archive.com/qmailtoaster-list@qmailtoaster.com/msg43073.html) to enable TLS 1.2 in Courier 4.1, after which testssl.sh reported that TLS 1.2 is working correctly. However, some of our users still reported errors using Outlook. So, the issue doesn't seem to be as simple as enabling TLS 1.2?
I'm currently working to replace Courier with Dovecot, since you mentioned the latest Dovecot version works for you.
