Microsoft Outlook stores all the mailbox data in OST, which is an offline data file. This file keeps all the mailbox data on local storage that helps users to work even when offline. Sometimes, this Outlook offline data file gets corrupted or turned inaccessible/orphaned. Also, a situation may arise when you need to move from one email profile to another profile. In such situations, you need to convert the OST file into Personal Storage Table (PST) file format. This is because OST file is linked to the profile in which it is created and cannot be directly imported into another profile.
This is where an OST to PST converter software, like Stellar Converter for OST, comes into the picture. This is a useful software for users who are looking to convert their OST files into PST as well as different formats, such as MSG, EML, RTF, PDF, and HTML.
