A few days ago, I tried lots of tools to reset OST file in Outlook. I found the best third-party solution, eSoftTools software. It’s very helpful for me to recover corrupted OST files and convert them into multiple file formats like Office 365, MSG, PST, vCard, HTML, Zimbra, Gmail, EML, EMLX, vCard, ICS, MBOX, etc. This tool is compatible with all Windows OS - XP, 7, 8, 10, and onward. It can recover all attachments of email like to, cc, bcc, subject, etc.
