It sounds to me like you are setting up Outlook to use port 465. In
the
setup screen, set the port to either "25" or "587". I am using "587"
with "starttls" Your "incoming mail port" will depend on how you have
Dovecot configured. I use port "143" with "starttls" for Outlook. YMMV
depending on your configuration.
You might want to consider posting the output of "doveconf -a" and how
you have Outlook configured.
To get things working with the client I had to set
"disable_plaintext_auth = no" and have them use port 143. Obviously,
this is not ideal. I could not get 993 working at all with the
client's version of outlook. However, on MS 365, outlook works just
fine.
It's insane.
OK, I had changed "ssl = yes" to "ssl = required" so having
"disable_plaintext_auth" is not such a big deal.
But I would still love to know why port 993 wasn't working at all for
this client.
