I'm using F14 and testing exchange mapi to connect to an exchange 2007 server. I'm currently able to receive, but unable to send e-mail.... Did anyone succed instead? In the mean time I opened the bug https://bugzilla.redhat.com/show_bug.cgi?id=674034 as it seems there is an upstream fix for openchange that could be a solution for a quite similar problem....
HIH others, Gianluca
