I have outlook 2003 setup in https mode and it works great. When i run exchange with the /rpcdiag switch and then try to add an additional mailbox it opens the additional mailbox in tcp/ip mode. This works fine when i am in the office but when i am not in the office i need it to connect via HTTPS and it does not. The server is exchange 2003 and the client is windows xp with office 2003. How can i resolve this problem?
