I want to say that if you are suffering from the OST corruption problem so use the best third-party tool that is ATS OST to PST Converter Software. The users see the preview of recovered mailbox along with emails, sent-items, deleted-items, drafts, outbox contacts, inbox, calendars, notes (To, Bcc, Cc, Subject, From, Object, Date and Time). This application not only recovers the data but also convert into Outlook PST file format without any difficulty. After the recovery process, the user migrates their data into several file formats such as PST, EML, EMLX, HTML, MBOX, vCard, HTML, vCal, MSG. If you are not satisfied with this program so you can return it within 30 days.
