I have a Yahoo Small Business Account that I am trying to sync with Zimbra Desktop. Everything on the mail and contacts side seems to work fine, but I cannot see my calendars. I don't see that I am getting any error messages, but no calendars are displayed...
Any suggestions?
Error Log:
Your Yahoo! account doesn't support calendar. Please either upgrade to add the support or turn off calendar sync option.
