OutlookFIX Repair and Undelete — Step‑by‑Step Recovery GuideOutlookFIX Repair and Undelete is a specialized tool designed to repair corrupted PST files and recover deleted or lost Outlook items. This guide walks you through understanding PST corruption, preparing for recovery, using OutlookFIX step‑by‑step, verifying recovered data, and preventing future data loss. Clear examples, troubleshooting tips, and best practices are included to help both beginners and advanced users complete a safe and successful recovery.
What is a PST file and why it gets corrupted
A PST (Personal Storage Table) file is Microsoft Outlook’s local data file that stores emails, contacts, calendar entries, tasks, notes, and other mailbox items. PST corruption can occur for several reasons:
- Large file size and reaching or exceeding PST format limits
- Unexpected shutdowns or system crashes while Outlook is writing to the file
- Hard drive issues such as bad sectors or file system corruption
- Virus or malware infections affecting Outlook data
- Faulty add‑ins or third‑party software interacting with Outlook
- Network interruptions when using PST over a network share
Understanding the cause helps choose the best recovery approach and reduces the risk of reoccurrence.
Before you start: safety steps and preparation
- Back up the corrupted PST file. Always work on a copy; never on the original file.
- Make sure Outlook is closed before running any repair tool.
- Check available disk space on the drive where the PST and recovery results will be stored.
- If the PST is on an external drive or network share, copy it locally to avoid I/O errors during recovery.
- If possible, note the Outlook version (e.g., Outlook 2016, 2019, or Microsoft 365) and PST format (ANSI vs Unicode) — this can affect compatibility and repair behavior.
Installing and launching OutlookFIX Repair and Undelete
- Download OutlookFIX from a trusted source and run the installer.
- Follow on‑screen prompts, accept the license agreement, and choose an installation folder.
- Launch the program with administrative privileges if you expect the software to access protected files or drives.
- Familiarize yourself with the interface: common panes include file selection, scan options, preview area, and recovery/export options.
Step‑by‑step recovery process
- Select the PST file
- Click “Open” or “Select PST” and navigate to the copied PST file.
- If you don’t know the exact location, use the built‑in search (if available) or search your user profile for *.pst files.
- Choose scan mode
- Quick scan: faster, useful for minor corruption or recent deletions.
- Deep/Full scan: thorough; scans file structures and attempts to rebuild heavily corrupted PSTs. Use when quick scan fails or when file shows severe corruption.
- Start the scan
- Click “Scan” or “Start” and allow the program to analyze the file. Scanning time depends on file size and scan mode.
- Monitor the progress; if the program reports read errors, consider creating a sector‑by‑sector image of the drive to prevent further damage.
- Review the preview of recovered items
- After scanning, OutlookFIX typically displays recoverable folders and items (Inbox, Sent, Contacts, Calendar, etc.).
- Use the preview pane to inspect messages, attachments, and contact details. This helps verify that important items are recoverable before export.
- Select items to recover
- You can recover the entire mailbox or pick specific folders/items. For selective recovery, expand folders and tick items you need.
- For deleted items, look for special folders like “Deleted Items” or a recovered items tree that groups orphaned messages.
- Choose recovery/export destination
- Export to a new PST: safest for importing back into Outlook.
- Export to MSG/EML formats: useful for archiving individual messages.
- Export to MBOX: if you plan to use another mail client.
- Save to a folder structure on disk if you prefer manual import later.
- Run recovery/export
- Click “Recover,” “Save,” or “Export” and select the target location (preferably on a different physical drive).
- Wait for the process to complete; verify the size and timestamp of the recovered file.
- Import recovered PST into Outlook
- Open Outlook, go to File > Open & Export > Open Outlook Data File, and select the recovered PST.
- Alternatively, use File > Open & Export > Import/Export to import items into your existing mailbox.
Verifying recovery and checking integrity
- Confirm presence of critical folders: Inbox, Sent Items, Contacts, Calendar, and Tasks.
- Open several recovered messages and attachments to ensure they’re intact.
- Use Outlook’s built‑in tools to check folder counts and search functionality.
- If calendar items or contacts are missing fields, verify the export format and try exporting again with different options.
Common issues and troubleshooting
- Partial recovery (some items missing): Run a deep/full scan and try alternative export formats (MSG vs PST).
- Read errors during scan: copy the PST to another drive or create a disk image and work from the image.
- Recovered PST won’t open in Outlook: ensure PST file size and format match Outlook’s supported limits; try creating a new PST and importing recovered items instead of opening the recovered file directly.
- Duplicate items after import: use Outlook’s Clean Up tools or run deduplication utilities.
- Attachments missing or corrupted: preview in OutlookFIX first; if corrupted, try rerunning scan with different settings.
Tips for faster, safer recovery
- Always work on a copy; preserve the original file for forensic needs.
- Use deep scans for severely corrupted files, but expect longer durations.
- Keep a log of actions and error messages — useful if you need professional support.
- Recover in stages: export top‑priority folders first (Inbox, Contacts, Calendar), then the rest.
- If PST corruption recurs, check underlying hardware (SMART status, run chkdsk) and scan for malware.
Preventing future PST corruption
- Keep PST files under recommended size limits or use Outlook’s AutoArchive.
- Avoid storing PSTs on network shares; keep them on local, healthy drives.
- Regularly back up PST files to external media or cloud storage.
- Keep Outlook and Windows updated; disable suspicious add‑ins.
- Consider migrating to Exchange or Microsoft 365 with server‑side mail storage to reduce PST reliance.
When to seek professional help
- If recovered data is incomplete after multiple attempts.
- When the PST contains critical legal or business records and data loss risk is unacceptable.
- If disk hardware shows signs of failure (strange noises, repeated SMART warnings).
- For forensic‑grade recovery where chain of custody and data integrity must be documented.

If you want, I can tailor recovery steps to your Outlook version (e.g., Outlook 2013 vs Microsoft 365), or walk through a recovery using a specific PST file — tell me the Outlook version and any error messages you see.
