Apart from exporting mailbox data to a PST using the Outlook Import/Export wizard, Microsoft does not provide any software or application to convert an Outlook OST file to PST format. You must convert an OST file to Outlook importable PST format since it cannot be imported into Exchange server, Outlook, or Office 365 accounts. This option, however, is only available if you have access to your Outlook profile.

An OST to PST converter software is frequently required in this situation. It transforms the Outlook Storage Table (OST) file to the Personal Storage File (PST) format, which contains mailbox objects including emails, attachments, calendars, notes, journals, and more. When Outlook can’t be accessed, shows an OST file error or the Outlook profile is either deleted/disabled from the server, an OST to PST file converter software, such as Aryson OST to PST Converter, can let you retrieve the mail items from an inaccessible or orphaned OST file.

It also aids in migrating an Exchange or IMAP Outlook OST mailbox to a new Outlook profile, Exchange, Office 365, Apple Mail, Thunderbird, or other email clients.
