In our company we have 2 mailservers, a Exchange 2003 and a lotus domino R5.(the are setup in coexistance) When people who are on exchange send a outlook meeting request to a person on the notes server (all users are using outlook as client, no notes client!) the buttons accept, decline, reject don't appear in the meeting request. I know that normally exchange 2003 converts automaticly meeting requests send to the internet to icalendar format. But It seems that the exchange server forwards the meeting request to Notes without converting to Icalendar format. When I manualy select forward as Icalendar format in outlook, the meeting request arrives on the other client as an ics file. Does anybody knows a solution for this?? regards Lode
