If the ESEUTIL.exe fails to restore the corrupted EDB mail items, then another best option you have at your disposal is Exchange Server. Hassle-free EDB recovery, quick email preview, and versatile email restoration paths are some of the advantages you can obtain by deploying this utility on your machines. I am really impressed with its EDB recovery.

I wanted an EDB file recovery tool, which can guarantee 100% conversion. After trying various software, I tried Exchange Server Recovery software. Being skeptical, I downloaded its trial version first that recovered my entire database at once. It proved what it claimed before even purchase.
