I'm getting issue with port 995 by using Microsoft Outlook 2016 only. The error on Microsoft Outlook showing "Your server does not support the connection encryption type. Try changing the encryption method". The error is only who is using Microsoft outlook2016. Kindly help.

Help us help you. Please include output of "dovecot -n" and any relevant log entries.
