Offline Storage Table (OST) file is an offline folder file in your Microsoft Outlook. It enables users to work offline and later synchronize changes with the Exchange Server, next time they connect.

OST files eliminate the need for multiple backup files and offer an easy way to access offline mail data. Offline storage tables can be used only with a Microsoft Exchange account or in a cached exchange mode.

There are times when your Microsoft Outlook application fails to find the OST file. This occurs when you try to play around or change offline folder settings. This error is displayed: “Not a valid path. Outlook cannot find OST file.”

You can solve this issue by converting your OST file to Personal Storage Table (PST) file. This conversion also helps you recover corrupt OST files. Your OST files require manual configuration, while PST files account for both offline and online mail data. Hence, PST files are preferred over OST files.
