Credit the following. Not my answer.
"Go to your calendar, switch your view to "By Category" then press CTRL+A to
select all, right-click and choose "Mark as Read".

I have an unread calendar event that I can't find. If I right click on the calendar folder and click mark all as read it still shows (1) as unread. I have downloaded all service packs and fixes. There must be something wrong with the .pst file, but I don't know how to fix it as it is on our exchange server. I have also searched for unread calendar events and it shows no unread events.
Please help!!
