Is there a safe way to recover data from an OST file?
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.

Your safety advice is the right starting point back up the OST first and work on the copy. That's the single thing that prevents a recovery attempt from making things worse.
Worth adding: an OST is a cache, not the mailbox itself. If the original Exchange account still exists, re-syncing can often regenerate the file — recovery is really for cases where the account is gone, the server is decommissioned, or the cache holds items no longer on the server.
For the recovery itself, Kernel OST Recovery scans corrupt, damaged or inaccessible OST files and lets you preview the mailbox in its original hierarchy before saving anything so you can confirm what's recoverable before committing. It recovers deleted emails, attachments, distribution lists and contacts.
It also handles the specific errors people hit, including Outlook Error 500 "Something Went Wrong," Out of Memory/System Resources, and the Cached Exchange Mode Grayed Out issue.

Saving options are broad: PST, EML, PDF, DOC, HTML, direct import into Office 365 or Exchange, and web clients like Gmail, Yahoo, Outlook.com and iCloud. Oversized PSTs can be split. Filters cover date range, folder, To/From and subject, and there's a graphical File Analysis Report.
The free demo saves 25 items per OST folder, which is enough to verify it reads your file correctly before licensing.

Yes, you can recover data from an inaccessible or orphaned OST file using a dedicated OST Recovery Tool. MailsDaddy OST Recovery Tool helps you to recover mailbox items, including emails, contacts, calendars, tasks, and attachments, from OST files when an Outlook profile is deleted, an Exchange account is disconnected, or mailbox data becomes inaccessible. It helps maintain the original folder hierarchy and important email properties during recovery, making it easier to access and manage recovered data. The tool is useful for both technical and non-technical users who want a straightforward way to restore their Outlook mailbox data.
