First of all, it's a good idea to move users away from exchange and outlook and their "standards" to something that's entirely based on true open standards. However, if your users are particularly cantankerous, below are some options.

  • About MAPI
  • Interesting development in OSS MAPI support: Brutus is an opensource implementation of MAPI. It's Corba based, pretty platform independent, and appears to be client-side only (?). Great name, too. :)
  • client - MAPI capable
  • server - MAPI capable
  • Not MAPI capable, but that doesn't mean it can't be interesting, right?
  • Unclear where it fits in the picture
  • Slashdot thread about replacing exchange
  • Making Outlook sort of useful. Why doesn't microsoft provide this kind of functionality?
