What Is An OST File In MS Outlook?

To figure out the way to open an OST file in MS Outlook 2016, we first need to understand what an OST file is.

Created in an Exchange server environment, OST files may pop some errors in front of the user while accessing these files offline.

Majorly reported by the users of MS Outlook 2016, this article covers the methods which can help resolve this problem.
