We have had Zimbra 3 MR2 installed for a couple weeks and it has been working great except when scheduling appointments other users free/busy schedule only shows "Unknown" even though they have other appointments scheduled.

Is this a known issue with MR2 or is something not configured right on my server?

All services are running and everything else seems to work fine. This is running the Commercial Trail version and is running on RHEL4.
