How to Use SoftTweak OST to PST for Fast, Reliable Email Recovery

Troubleshooting Common OST to PST Issues with SoftTweak Software

1. Installation fails or software won’t open

• Check system requirements: Ensure Windows version, RAM, and disk space meet the tool’s minimums.
• Run as administrator: Right‑click the installer or app and choose Run as administrator.
• Disable antivirus temporarily: Some AV tools block installers — temporarily disable and retry.
• Re-download installer: Corrupt download can cause failure; download from the official SoftTweak site and verify file size.

2. OST file not recognized or “invalid OST” error

• Confirm OST integrity: Open the OST in Outlook (if possible) to verify it’s not corrupted.
• Use the correct OST type: Ensure the OST is not an Exchange cached copy locked to a different profile/account.
• Copy locally: Move the OST to a local drive with full read/write permissions before converting.
• Try SoftTweak’s repair option: If the tool offers a scan/repair phase, run it to rebuild headers.

3. Conversion hangs or is very slow

• Check file size: Very large OSTs take longer; split large mailboxes by exporting smaller folders if possible.
• Close other apps: Free up CPU/RAM by closing heavy programs.
• Enable incremental mode (if available): Use any option to convert only new items.
• Check disk I/O: Ensure target drive has sufficient free space and is not degraded.

4. Partial conversion or missing folders/items

• Verify filters/settings: Make sure no date range, folder selection, or item-type filters are excluding data.
• Check logs: Review conversion logs for skipped items or errors.
• Try alternate recovery modes: If SoftTweak provides Standard vs. Advanced scan, run Advanced to recover more items.
• Export problematic folders separately: Convert high‑risk folders (Inbox, Sent Items) in separate runs.

5. Output PST not opening in Outlook

• PST compatibility: Ensure PST format version matches Outlook version (ANSI vs. Unicode).
• Use Outlook’s Import tool: Import the PST via Outlook’s File > Open & Export > Open Outlook Data File.
• Repair PST with ScanPST: Run Microsoft’s Inbox Repair Tool (scanpst.exe) on the generated PST.
• Check file size limits: Older Outlook versions have PST size limits (~2 GB for ANSI).

6. Error: “Permission denied” or access errors

• Run tool as admin: Start the converter with elevated privileges.
• Check file attributes: Remove read‑only flags on OST/PST files.
• Verify path length: Use shorter paths — long file paths can cause access errors.
• Antivirus/backup conflicts: Temporarily pause services that lock files.

7. Corrupted items (attachments missing or unreadable)

• Use deep scan mode: Advanced recovery often rebuilds attachments.
• Check original OST with Outlook: If corruption exists there, repair OST first.
• Try exporting to EML/MBOX (if supported): Alternate formats may preserve attachments better.

8. Licensing or activation problems

• Confirm license key: Re-enter the exact license key and check for typos.
• Internet connection required: Ensure online activation can reach licensing servers.
• Contact support with order details: Keep purchase ID and email ready.

9. Logs and support

• Collect logs: Enable verbose logs (if available) and note timestamps of failures.
• Screenshots and error codes: Capture exact error messages to share with support.
• Reach SoftTweak support: Provide OST sample (if not private), log files, software version, Windows and Outlook versions.

Quick checklist (try in order)

1. Run app as administrator.
2. Copy OST locally and ensure read/write permissions.
3. Disable antivirus/backup during conversion.
4. Use Advanced/Deep scan mode.
5. Check filters and output PST version.
6. Repair resulting PST with scanpst.exe if needed.
7. Gather logs and contact support if unresolved.
