Hi,
We use Zimbra mail 7 and one of our users uses a Mac. He uses iCal to import his calendar it worked fine for a long time but now he sometimes gets errors
Te error message is: 400 operation caldavaccountrefreshqueueableoperation error
I've added a screen of the error as attachment. Does someone know a solution for this error?
What we've tried:
- Deleting the iCal cache
- Removing his calendar and adding it again.
- Putting off alarms for calendar items.
Thanks in advance.
