I'm looking for the most efficient way to open a pst file in Outlook. One day, my computer was infected with a virus, and my data became corrupted, so I'm looking for the query. Fortunately, I came across the eSoftTools Outlook PST Recovery Program, which recovers and migrates PST file data quickly and easily. The best feature of this program is that the PST file has no size restrictions. It can also recover PST files in ANSI and UNICODE formats. As a result, I was able to restore all of my files from 2007 to the present using this program. In addition, it was able to recover password-protected PST files.
