Description (partial)

The MAR logs do not show enough information to determine certificate CN mismatch problems.

It displays:

Thu Jul  9 15:01:32 2020 Info: Failed to access mailbox of user@example[.]com using server: localhostname[.]example[.]local, impersonator: username. Reason: The appliance is not able to read the user's mailbox. Error: Please check host localhostname[.]example[.]local is valid exchange server address.

It should display more details of certificate problems like:

Thu Jul 09 15:01:32 2020: WARNING: Failed to create cached protocol with key (u'https://localhostname[.]example[.]local/EWS/Exchange[.]asmx', Credentials('username', u'********')): hostname 'localhostname[.]example[.]local' doesn't match either of 'hostname[.]example[.]com', 'another-hostname[.]example[.]com'

- Mailbox Autoremediation (MAR) is enabled
- The hostname of the MS Exchange Server configured on the ESA does not match the hostname present on the Common Name (CN) field of the certificate presented by the Server
