Jonathanp1,

Did you ever get this resolved? I have the same issue after migrating to O365 over the weekend. None of the voicemail to emails are working, getting exact same issue as you.

A Quick google says you must have postfix 2.9+ (http://serverfault.com/questions/516841/how-to-configure-postfix-on-ubuntu-to-relay-emails-through-office-365-smtp-wit)

You can see what version you have with:

postconf -d | grep mail_version
