If I understand you correctly, you are saying people internally cannot
connect from that specific internal subnet. This is because internal
requests to an outside interface on their router cannot work because the
router cannot do a "U-turn". This is a NAT limitation. Easiest solution is
to connect to the internal name of the server or use it's internal FQDN
name, such as https://internalname.domain.com/exchange.
