I am attempting to connect outside users to the exchange server using RCP over HTTP. I can get it to work inside the office but not from the outside. I checked the connection status in outlook at it was tcp/ip and I know that is not right. Everything seems to be right according to the instructions I have found on microsoft. I read on here that if an ssl cert popped up it would stop outlook in its tracks. I turned off ssl for RPC and can now connect through http://server.domain.com/rpc with out the cert popping up. Any help would be appreciated.
