I have new users that show up as yellow (Status Unknown) when trying to schedule a calendar event. Their settings are default, same as the other users (Allow both internal and external users to see my free/busy information and Allow both internal and external users to invite me to meetings).

Is there a limit to the number of corporate accounts or am I missing a setting? This only happens to new users.

All new users run Windows 7 SP1
Latest version of Zimbra Desktop installed
Mail accounts on a mail server specifically for Zimbra
