Hi MMASLOUH,
Sophos XG does only support the following authentication methods.
PLAIN
Digest MD5
CRAM MD5
To authenticate against Microsoft Office 365, one of these authentication methods needs to be configured on both ends.
If these methods are configured, then try test connectivity with Certificate as 'none'.
