Calendar not importing .ics
Calendar is not accepting .ics invites. Here's the scenario:
I receive an email invite to a meeting (they use outlook exchange). I quicklook the .ics file to check the date/time/etc... It's all correct. I then double-click the .ics file and iCal (now Calendar) opens. Nothing happens: it doesn't add the file, move to the day of the event, etc...
This only happens occasionally and it's driving me nuts. Most of the time meeting invites work, but every so often they won't. Or they will but then any updates won't be accepted.
Any thoughts?
