I deleted three large .pst files sometime within the last few months because I thought I was finished with them.
I didn't realize that the mail I put in them was moved off the server permanently into the pst files. Now they need these for a lawsuit, and I need help finding them.
I am pretty sure the files were on my desktop and permanently deleted instead of the recycle bin.
You can try recuva, but as they were deleted some time ago, the sad fact is that they may have been overwritten beyond salvation. I'm noit sure what other help we can give you until you try the product supported on this site, which your post makes no mention if you have attempted recovery yet or not. The best thing to do it to remove the drive from any functioning computer until such time that you can try recovery they longer you wait the hard it will be for ANY program to recover the files.
