Situation – I am in a main office and we have 12 remote offices. The remote offices use our exchange 2003 server with outlook 2003 setup with POP/SMTP. The head person in each office has asked for a shared office calendar be setup for their office. The offices are connected to the Internet by DSL but are not on a VPN to the main office. What is the best way to setup these 12 remote offices so each office has their own shared calendar? My thought is to take them off POP/SMTP and setup RPC over HTTP. Will that work? Is this how most folks take care of this type of situtaiton? Also, if this is the best solution can you point me to good documentation for setting this up on both Exchange 2003 and Outlook 2003? By the way – does the RPC/HTTP require SSL?
