The availability panel for my corporate calendar no longer works after installing Yosemite. I get a message that says "This calendar does not support availability." This was working before I installed Yosemite. Is there a configuration I need to change?
I have the same issue. Without this, iCal is pretty useless for my purposes. All still working with Thunderbird on Mac.
I have the same issue as well.
The fact that this is still broken is a fricking joke
Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.
Or you can use your Apple ID to register with this site and go the Apple BugReporter. Supposedly you will get an answer if you submit feedback.
This is actually working for me since a short little while (few weeks). There is now a small button under the meeting participants to 'check availability' and that works like a charm.
