Hi NG!

We've a problem with one of our users free/busy options. We can open the
calender of the users and see his appointments but when we'd like to see his
free/busy times (during creating a appointment) we're getting the error:

No information. No /free/busy information could be retrieved!

Once we also recognized the error message:

Unable to update public free/busy data. You do not have permission to log on.

We've also tried to view the free/busy times of another user on the same
server in the same mailbox store with success. So we only have this problem
with one user account!

Any ideas???
