I have a user who, when attempting to create a new appointment in Outlook,
cannot do so. There is no error or anything. It just won't allow that to
happen. She also cannot accept invitations to appointments. She clicks on
the Accept button and nothing happens. No one else, ever, has or has had
this problem before. This is a newly installed computer, and on her
previous computer this was not an issue.

I'm guessing the cause is something simple. Has anyone seen a problem like
this before?

Thanks in advance!
