OST file is an Outlook data file that is created when you configure the Outlook with IMAP, Exchange, Office 365, and Outlook.com accounts. It saves a synchronized copy of mailbox data on your local system. You can perform various actions such as reading emails, deleting emails, composing new emails, etc., even in the absence of Internet connectivity or access to the server.

However, at times, you experience a situation when the OST file gets corrupted. Some signs of OST corruption are error messages during OST file synchronization, missing items from OST file, etc. There are various factors that can lead to OST corruption such as bad sectors on hard drive, incompatible Outlook add-ins, oversized OST file, etc.
