Sync error with calendar

[twol174]

Just installed Zimbra Desktop yesterday. Tested with my Yahoo Mail account. At first it asked me to update to the new calendar, which I did. Then It synced my account. Mail was synced, Contacts were synced but Calendar waqs not. I received the following error message:

Failure communicating with remote server. Please try again later.

Debug message: Expected [-3], read [-1] at line 1

Exception:
