How to open an calendar email from my inbox?
 

I use to be able to click on an email calendar invitation and it would
automatically be added to my calendar or be removed, if it was a
cancellation. I was upgraded to Outlook 2003, and now I get an error
message, when I try to open the invitiation. The error message states that
it "cannot create file. Right click the folder you want to create the folder
in and then click properties on the shortcut menut to check your permissions
for the folder.

.. I tried this, and didn't see naything that would grant me rights to open
the calendar invite from my inbox. Please advise.
