Count of new items in calendar folder

[Lauren]

One of my users is experiencing something that the other
100 users in my company isn't. For some reason, in the
calendar folder, there is a number next to "Calendar"
(Ex. "40" in a blue color). I know that when you see a
number nex to "InBox" it indicates how many new messages
there are. However, I can't tell what messages are new in
the calendar folder. Is there a way to tell this or,
better yet, is there a way to turn this off for the
calendar folder? Any help would be greatly appreciated.

Thanks,
Lauren
