The outlook not connecting to the exchange server in both cases can be a certificate issue. The SSL certs must be trusted (either from a commercially trusted CA or you import the cert into the computers trusted root CA folder).

OWA access, is a permissions thing. Somewhere the permission isnt set right for the user(s) that cannot access OWA. Has anything changed in either environment?
In Outlook, click the "File" menu option and see if there is a check mark beside "Offline". If there is, click "Offline" in the File menu to allow the client to connect again.

You should have both Exchange URLs (internal/external) within the local DNS at each office.
