Meeting invitations from Exchange users in other systems go directly into my calendar when I accept. Whats up with that?
Because Exchange meeting invitations are in the standard .isc format, invitations from other systems using that format can be recognized and automatically accepted by Outlook. Likewise, meeting invitations sent from Exchange can be accepted by users of other .isc-compliant calendar systems, like iCal on the Macintosh. Just remember that meeting information from different systems becomes unlinked from the system that originated it and looks just like an activity you set up yourself.
