I would like to bring the following kb under youre attentionhttp://support.microsoft.com/kb/266418
So if youre are ever tempted, in a 2 user setup for example, to use a small business server (this has exchange installed on it)and install terminal services (to be able to work form home) .
Then when you add the magic ingredient Outlook.
Now when you try to use the email button on the contact card i noticed my NAV client just disappeard magicly. In 3.6 i got an mapi nothing saying error .
So just to save you some time, installing outlook on any pc with exchange on it will cause mapi to fail on that pc.
