After reinstalling Windows, my old OST file has become inaccessible, and I can’t open it in Outlook anymore. I need a way to restore all my mailbox items — emails, calendars, and contacts — from this OST file back into a readable format. What’s the most efficient method to restore data from such OST files without using Exchange or Outlook connectivity?

It is very easy to restore Outlook data from an inaccessible OST file with the right approach. Users can do it in two ways: manually and with a professional tool. If you go the manual way, it couldn't be the right approach because it can't restore complete data and does not maintain folder hierarchy. The right approach is to use a professional tool like FixVare OST Converter. It can easily restore data without compromising data integrity. It allows restoring single or multiple OST files at once. It is user-friendly, which makes it easy to use.
