Hi people...  
In a few days ago I was working in my pc, and changing for erroneous the permission in the folder where Outlook save 
all the messages...  
Well, when I was trying enter at my Outlook this program say  
"This program do a invalid operation and it will close..." (so so)  
This is a problem of my windows (2000) or windows 2000 have this problem...?
