New Outlook Outgoing Server Settings SMTP authentication after server 2017 Plesk upgrade

Symptom:
Outlook fails to send messages with error "Outlook doesn't support any of the available authentication methods".
After Plesk server upgrade to Plesk Onyx.

Fix:
Check if Outlook Outgoing Server Settings are configured as:

My outgoing server (SMTP) requires authentication.
Log on to incoming mail server before sending mail.

Change this configuration. It should now be:

My outgoing server (SMTP) requires authentication.
Use same settings as my incoming mail server.
