I've been converting my corrupted OST emails into PST files using vMail OST to PST converter to repair and recover my data. One of the best features of this program is the ability to split a PST file into smaller PST files. With the use of this application, you may save recovered OST files in a variety of formats, including PST, EML, EMLX, MSG, MBOX, vCard, vCalendar, and HTML, along with all of the email item properties. It is designed to function on all MS Outlook office-365 versions, including 2016, 2013, and all earlier versions.
