Next to the check when entering the settings there is a question mark circled to the left. Clicking that gives a menu with 'Collect Diagnostics' & 'Contact Support'

When the popup indicates a connection issue I push 'support' button and error suggests a certificate issue. Two options appear at this point: 'Talk to Agent' & 'OK'. If you 'talk to an agent' you can do more advanced troublshooting like sending an Outlook error log file to them. You might try this.

I could be wrong but I think Outlook for Android must be very sensitive to the encryption ciphers being used and the SSL/TLS versions. We use Let's Encrypt certificates - I wonder if it's anything to do with that.

Try this script (replace with relevant user, password, & host) from the command line of the server. It will yield what version of TLS you're running.

<script>

#!/bin/bash

function imapscript () {
echo "a login $1 $2"
echo 'a logout'
sleep 1
echo 'quit'
}

user=some...@mydomain.com
pass=***********
host=mail.mydomain.com

imapscript "$user" $pass  | openssl s_client -crlf -connect $host:993

</script>

    We have a customer trying to connect to his qmail-toaster
    email account using the MicroSoft Outlook app on an Android
    phone. He keeps getting bounced off with the message 'can't
    connect to server' or 'can't login'.  I did some research on
    the MS forums and apparently this Outlook app only connects
    with SSL (no STARTTLS) and TLS 1.2 or higher.  If the
    mailserver tries anything else first the connection is dropped.

    Is there any known work-around or configuration adjustment
    needed to get this Android Outlook app to work with the toaster.

    We're running qmail-1.03-2.2.qt.cdb.el7.x86_64.rpm

    Thanks, Jeff
