|Allow me to clarify and update.|
I have a 2 gig .pst file. I have a 10 gig older .pst file. I access the older file for stored information. The 2 gig resides on my workstation. The 10 gig resides on the server. I had the 10 gig open in Outlook. When I attempted to close the folder, I received an error message. When I attempted to open the 10 gig, I received an error message. Following advice I found on the Internet, I created a new profile and imported the original 2 gig file into the new profile. I no longer have the 10 gig unopenable file in the new profile. Instead, I have the 2 gig file twice! I cannot close or remove the copy.
