iCal not syncing with Exchange calender in OS X 10.10.2

iCal is not syncing with an Exchange-based calendar with the OSX 10.10.2 update on my 2012 Macbook Air.

Any calendar events added since the software update are not replicated to the main Exchange account, nor are new events made in other calendar programs replicated back to iCal. This includes calendar events made on the Apple Calendar app on an iPhone 6/iOS 8.1. iCal shows events made before the software update, just none after. Google Apps-based calendars in iCal are not effected, only Exchange-based ones.

I have deleted and re-authorized the Exchange calendar in the Calendar applications on the Mac and the iPhone, and this problem still exists. My workaround is to abandon iCal and to use BusyCal 2 for OSX, which does sync with the Exchange-based calendar. BusyCal 2 does sync with iPhone Calendar, so the issue is specifically iCal in 10.10.2

1. Is anyone else experiencing this problem?

2. Does anyone have a potential solution?

Thanks in advance,

Wayan

OS X Yosemite (10.10.2)

Cheers everyone

My situation is similar. I have an iPhone, and iPad, an iMac and my MBA. Calendar sync with my work exchange calendar is working flawlessly on my iOS devices and my iMac (running Sierra). However, on my MBA (also running Sierra) I have sync. issues. Any item added on my MBA calendar will sync across devices but when ever I add/change my calendar on one of the other devices it does not sync to my MBA. I have tried just about anything, incl. the proposals listed in this thread. The remedies seem to result in a snap-shot update to my MBA but after initially catching up it refuses to down-sync.?

Thanks Wayan_V for your support!

The "solution" is actually a temporary workaround for an issue which exists for *two* years now (and is still an annoyance - I just lost unsynced calendar entries). In my case, I have to run the workaround every few days - this is just not a professional way to work.

I don't know how Apple looks into these forums, so here is the message: APPLE, FIX IT - NOW!!

I am seeing the same issue. Tried deleting the cache and removing and re-adding the Exchange calendar but no luck.

I'm having the same problem with iCal not synching with Exchange, after updating to OS X 10.10.2 (yosemite). Very frustrating! I hope this is fixed soon or I'll need to find another calendaring solution.

I tried deleting my Exchange account and setting it up again anew. To no avail. It still doesn't synch properly (although my iPhone calendar appears to work properly with Exchange). The problem appears to be with ical in OS X.

Thanks, Wayan! I'm giving up on iCal and will take your recommendation to switch to BusyCal. I've been wrestling with iCal issues for too many years now. Thanks for the tip!

Again, many thanks, Wayan! I just started a 30-day trial of BusyCal. Easy setup and appears to work better than iCal. Now, if I could get more RAM for my Macbook Air, I'd really have this machine working well!

I'm having the same issue across multiple macs running 10.10.2. :-(

Apple, please don't make me use Outlook...

Outlook for Mac is just as bad, if not worse (in my opinion). I purchased both BusyCal and BusyContacts. Much, much better experience. And the developer clearly deserves compensation for getting these right (since Apple can't seem to do so). I just wish there was a BusyMail app too!

Hey everyone, thanks to this thread, we now have a solution. Or at least it worked for me.

Clear Calendar Cache:

1. Go to system preferences and open internet accounts. Selected the Exchange account and turn off calendar.

2. Close iCal and any other calendar application you might have running

3. In Finder, go to HD/Users/User Name/Library/Calendars and delete the Calendar Cache files (may need to empty Recycle Bin)

4. Restart iCal, which will rebuild the caches

5. Turn on your Exchange calendar

BusyCal is a good option for sure. I like the look of iCal a little better, so I'm going back to it now.

Sad to hear that MGarito. Did you empty Recycle Bin? The first time I tired this, I had to shut down several calendar agents via Activity Monitor that were running in the background, before I could fully delete the caches.
