Outlook with Dovecot

12 Dec 2020


      dovecot-2.3.11.3_1
Hi group, I have a problem with connecting Outlook 2019 client to my
server (BSD 21.2).
Running Postfix and Dovecot.
[all.log]
Dec 12 16:53:41 poseidon dovecot[36185]: imap-login: Disconnected (auth
failed, 1 attempts in 2 secs): user=elise@xxxxx.xx, method=PLAIN,
rip=82.x.x.x.x, lip=10.x.x.x, TLS: Connection closed,
session=<U62faUa24N5SsH9H>
Providing the correct email address and password.
Strang thing is that with Thunderbird it all works fine; only Outlook is
refused.
tx, Elise
