Looking for a safe way to recover data from an inaccessible OST file? Try the Aryson OST to PST Converter Tool, which helps you convert OST files into PST format without Outlook. It's ideal when your Outlook profile is deleted or the Exchange Server is down. The tool also allows you to import OST to Office 365, so your emails are always available online. You can preview your mailbox items before converting and choose which data you want to export. The best part is that it also supports converting encrypted and orphaned OST files. Furthermore, the software is fully compatible with all versions of Windows and Outlook.
