The Outlook data file which was absolutely fine yesterday has now turned into a 0KB file. This morning when I tried to open it, I received an error message unexpectedly. So I checked the file size and found it's 0KB. I knew the Inbox Repair can't help me, however, I tried it and had no luck. I found so many articles on the Internet. Some say recovery is impossible from a 0KB PST file. And some recommend using a professional solution for recovery. Is it really possible to recover from a 0KB PST file? Please help me.
