I am on an Exchange 5.5 server intranet. When I send a MsOutlook 2000 (workgroup) appointment to someone on MsOutlook 2000 (internet) not on our intranet, the appointment arrives as text. Microsoft support says that this is know problem with Exchange, there is not fix. I have a hard time believing that no one knows a way to fix this and that you can only send appointments to folks on your intranet. Any suggestions or feedback, who to talk to, where to go?
