Last weekend we had our server upgraded from 5.0.4 to 5.0.8.

Since that time a user, let's call him 'Scott', gets invited to meetings but is no longer able to answer "Accept" "Tentative" "Decline" to an invitation. and only receives a .ics attachment.

More curiously, if you go to add Scott as an invitee to a meeting he no longer displays any free/busy info even though he has events in his calendar.

This is tested on Mac/Firefox 3 and also with the latest SeaMonkey (which I use for my own testing)


Thanks
