Yes, there is a safe way to recover data from an OST file without directly modifying the original file. First, create a backup copy of the OST file and work with the duplicate to minimize the risk of further data loss. For corrupted, inaccessible, or damaged OST files, Aryson OST Recovery can scan the file using Standard, Advanced, or Deep recovery modes and preview recoverable mailbox items before saving them. It can recover emails, contacts, calendars, tasks, journals, and other Outlook data. The recovered data can be saved in formats such as PST, EML, MSG, MBOX, DBX, and Archive, allowing you to access the recovered information separately from the original OST file. Aryson also provides a preview option, so you can verify the recovered mailbox items before saving them.
