Thank you so much! that was such an easy fix that i would have never figured out. BTW are you familiar with Outlook? I tried to archive my Outlook files to a file on my computer and now I cannot open Outlook. I get this box that says

"Cannot open your default e-mail folders. File access is denied. You do not have the permission required to access the file C:\Users....\AppData\Local\Microsoft\Outlook\Outlook.pst"

Can you help?

Thank you
