I upgraded to a new 64 bit windows home 7 version. I hastily backed up my Outlook and I can't remember how I did it. I do know that the file was saved on my external hard drive and is identified as type of file : file It did not save in a pst format. Now when I try to open it, I can't get anything. I tried to convert it by forcing Outlook to open it on the external drive, but it would not do anything. I was previously running xp pro for the backup.

So any suggestions? Please
