Hello Mr. Fyodorov and Mr Bubba G, Thanks for your advice. MAPI is build on COM technology, so if my program runs on non-Windows system (Linux/Unix...), I can't use MAPI. Is there any way for client in non-Windows system like Linux/Unix to connect and operate with MS Exchange server? I think MS Exchange server is a well-known massaging server and MS hopes users to use their services. To do so, MS Exchange server defined standards/protocols that clients (non-Windows client) must follow to work with MS Exchange server, didn't it? If there are those protocol, can you tell me where I can find them? Thanks and regards Qiang Peng.
