Yep already tried it last year, (and yeah sometimes the simpliest things are the ones we don’t try). This was actually the first recommendation someone gave me and it didn’t do a damn bit of good. As I said I have even gone to Microsoft for help and I have downloaded 2-3 programs from them they claim can fix .pst file problems, but none of those programs worked. The last result is sending these CDs to Microsoft.
Thus I no longer back up my mail to a CD, I only back up to my HDD and my zip drive.
