From Outlook, when I tried to access archive.pst, I was told the file was too large. When I tried to simply navigate to the file's location, the file would not, as such, show up, but the folder had over 2 GB in it. I tried to access it with Adobe Reader. It didn't work, and the attempt may have contaminated the file. The file contains archived e-mails that I have sent, I think. How can I access the file?
