Synch with Yahoo Calendar. Can no longer sync since upgarde to Mountain Lion. When I open Calendar this is what I see: The URL //caldav. calendar.yahoo.com/principals/users/my name/ encountered HTTP error 302. Make sure the URL is correct.
MacBook Pro with Retina display, OS X Mountain Lion
Mountain Lion Calendar now gives this message:
The request (CalDAVRefreshDelegateListQueueableOperation) for account “Yahoo!” failed.
I have exactly the same issue. I have called Apple Support about it.
I discovered a manual temp fix. If you go into Calendar Preferences and highlight the Yahoo account and switch off the "Enable this Account" box, and then check the box again to Enable it, the calendar will be updated. It will not update automatically. You will still see the message about "failed" but at least for the moment it is updated. This IS a Mt Lion issue as I have no problems on one computer still on Lion or any ipad, iPhone devices. Let me know if Apple Supoort has a solution.
same here, new mac air with Mountain Lion. Iphone 4s and wifes Ipad and iphone 4 work like a champ.
Try this:
Instead of signing up for calendar, sign up your yahoo e-mail. Then go to system prefs>Mail, Calendar and Contacts
There you can check Calendar and if you wish un-check e-mail.
Calendar has been syncing with no errors since I did this.
Success!
