What does your APM log say when you attempt to authenticate? If you do not have a lot of APM for other applications it should be manageable by following the log in cli bash

tail -f /var/log/apm

 

Bear in mind that your exchange servers might not have been configured for basic auth.

 

I have seen external MAPI work well with APM, this was configured with NTLM for validating the klient and then kerberos to the backend server.
