Calendar - Exchange sync issue

I'm having a problem with Calendar and Exchange syncing (my company uses Exchange 2010), with the following error:

"Calendar can’t save the event “Item title” to the Exchange server.

The account "Exchange" currently can’t be modified. To discard your changes and continue using the version of your calendars that’s on the server, click Revert to Server."

The options on the dialog box are:

Revert to Server

Try Again

Ignore

Syncing in general is working, i.e., items added in either system show up as they should. And, I'm not actually changing anything on the items on my MBA. The error pops up apparently randomly--so far, at least, I haven't been able to identify a pattern. I've checked credentials, which seem to be correct, and I've verified that time zone settings are turned on as I think they're supposed to be.

Any ideas?

Option 2, for people that like getting down to the actual details, rather than using the UI:

Hope this helps.

I'm really disappointed of Apple. It's incredible that they are unable to fix this issue even in a new OS version (Mavericks). I'm still having issues with Calendar.

Same here! iCal is playing ghost with me, seems like it does something in the background but does show any calender entries.

MBP, Exchange 2010.

Any luck syncing Exchange Notes with Apple Mac Notes on Mavericks?

Check your time zone and location. That seems to fix mine.

Have you had any luck fixing this problem?

Clear the cache file solves my problem. Finally 🙂

Went to ~user/Library/Calendars and deleted Calendar.Cache file

Deleting "Users/your-user/Library/Calendars/Calendar\ Cache" file worked for me. (Remember to Close Calendar before deleting the file)

I had to manually change the time zone from Mexico City to Chicago. They are both in central and it now syncs with exchange.
