SyncError: No suitable authentication method found for SMTP server. Error: No suitable authentication method found.. (#100000010)

Cause

SMTP configuration error "STARTTLS extension not supported by server" occurs because you are using non-secure SMTP configuration on the exchange server. If the secure connection box is checked, it will give the error: "No suitable authentication method found for SMTP server". This occurs because the exchange server is configured to use unauthenticated SMTP mode.

Resolution

In order to resolve this issue, uncheck the secure connection box in the SMTP settings page and remove the SMTP username and password. This will allow you to send the test mail successfully without the error.

Administrators can also try putting the SMTP username and leaving the password field blank.
