Quick Tips for Reliable OST-to-PST Migration with Software Imperial OST to PST Converter
1. Prepare before conversion
- Backup: Copy original OST files to a safe location before using the tool.
- Close Outlook: Exit Outlook to avoid file locks and partial reads.
- Check file integrity: Note file size and run a quick disk check if files are unusually large or corrupted.
2. Use the right edition and settings
- Choose correct license: Use the edition that supports batch conversion and large OST sizes if you have many or big files.
- Enable folder-structure preservation: Keep original mailbox hierarchy to simplify post-conversion access.
- Select selective filters: Use date-range and folder filters to reduce output size and speed up conversion.
3. Handle encryption and orphaned OSTs
- Orphaned OSTs: If the OST was tied to a deleted Exchange profile, use the tool’s “open/orphan OST” or profile-less mode.
- Encrypted OSTs: If the OST is encrypted or profile-bound, enable any built-in decryption/profile-reconstruction options; if unavailable, recreate the original Outlook profile on the source machine first.
4. Manage large files and performance
- Split output PSTs: Use the split/size-limit option to create multiple PSTs (e.g., 10–20 GB) to avoid Outlook performance issues.
- Batch processing: Convert multiple OSTs in parallel only if your machine has sufficient CPU/RAM; otherwise process sequentially to reduce errors.
5. Verify results and post-conversion steps
- Open PST in Outlook: Attach the output PST to Outlook and verify folders, email counts, attachments, and calendar/contacts.
- Spot-check items: Randomly check messages (headers, attachments, metadata) across folders.
- Repair if needed: Run Outlook’s Inbox Repair Tool (scanpst.exe) on PSTs showing issues.
- Export/import as needed: Use Outlook’s export/import for filtered moves or to rebuild profiles.
6. Troubleshooting common issues
- Missing items: Re-run conversion with no filters and enable “include recoverable items” or “deep scan.”
- Access denied / file locked: Ensure no background process (Outlook, backup software, antivirus) is using the OST.
- Slow conversion: Increase available RAM, close other apps, and convert smaller batches.
7. Security and compliance
- Work offline: Perform conversions on a secure, offline workstation when handling sensitive mailboxes.
- Audit output: Keep logs enabled and store conversion logs with audit metadata (date, operator, OST filename).
- Retain originals: Keep original OST backups for a retention window required by policy before deletion.
