It's not possible to open an OST file directly in Outlook because OST files are linked to an Exchange, IMAP, or Outlook profile. If the Outlook profile is deleted or server access is unavailable, the OST file becomes inaccessible. In such cases, eSoftTools OST to PST Converter Software is an effective solution. This software allows you to easily scan the OST file and convert it to PST format, which can then be opened in Outlook without any issues. The tool safely recovers emails, attachments, contacts, calendars, and other mailbox data and also provides a preview option, allowing you to check the data before conversion.
