Microsoft Outlook stores mailbox data in Outlook OST (Offline Folder) or PST (Personal Folder) file based on the email type. When a user configures an IMAP, Exchange, Outlook.com, or Office 365 email account in Outlook, it creates an Offline Storage Table File (OST) for mailbox storage. For POP-based email account, Outlook uses Personal Storage Table (PST) file to store mail items.
Unlike PST, the OST file is encrypted and can’t be accessed or imported into other Outlook accounts. Instead, you need to convert the OST file to PST format or export the mailbox items from an OST Outlook profile to PST format using Outlook Import Export Wizard or an OST to PST converter software, such as Stellar Converter for OST.
The software comes in handy when you can’t access Outlook and OST file becomes inaccessible or orphaned. Stellar Converter for OST helps you restore the mail items from such inaccessible or orphaned Outlook OST files to PST and other multiple portable file formats, such as EML, PDF, RTF, MSG, MBOX, DBX, and HTML.
