I can't configure my business MS Exchange on my Mac although I can with the same settings on my iPhone and iPad. Do I need to configure something more of bypass some kind of setting or something like that?
Communicator isn't working as well, so that's why I think it's about a general Mac problem configuring my Exchange account...
EDIT: I try to connect with MS Outlook for Mac 2011. Is Mail Lion 100% compatible with Exchange?
