Milly:
I posted on this exact problem on May 28 under a post titled "New
Appointment: messaging interface has returned an unknown error"

The error message reads: "The messaging interface has retruned an unkown
error. If the problem persists, restart Outlook." I only have Office Beta 2
running on my machine.

I have completely uninstalled, restarted, and reinstalled office 07 beta 2.
That did not fix the issue I still get the same error message if i try to
make a new appointment, either from the menu or by right-clicking on the
calendar date and selecting new appointment.

1. What is the exact error message?

2. Only one version of Outlook can be installed and active at one time.
