I have the most ridiculous problem with a client's computer. They have an Outlook PST file that is over 6 GB (unusual, I know). The weird thing is that Outlook seems to open it fine and can work for the most part. If I try to export the PST though Outlook freezes the computer and I have to do a hard reset. If I try to make a new profile and import it, same thing. I am now trying to simply copy the PST file to another location and it is now hanging at the very end with "50 seconds remaining" and has been that way for an hour. The computer seems incredibly slow during this copy process too! What in the heck can be doing this to the PST file not allowing me to do ANYTHING to it? I tried the MS PST repair tool and it froze on step 1.
