How to repair large Outlook 2007 PST on Windows 7?

User was running Windows 7, with Outlook 2007, 20 GB PST. User has two email accounts, 1 may be an IMAP, 1 may be POP, or both can be POP (I'll check if necessary). No Exchange accounts. Outlook wouldn't start, so I used SCANPST to repair (took hours, of course). Outlook ran slowly, but now is getting stuck again. Ran Windows 7 error checking, with "Scan For and attempt recovery of bad sectors".

My thought was to:
- Restart with startup items turned off.
- Upgrade to Office 2013
- See if Outlook will open the PST
- Run SCANPST again
- Does SCANPST compact the PST ?
- Should I compact after running SCANPST ?
- If I get Outlook Running, should I move old messages to separate PST files, a year at a time?
- Any 3rd party repair tools that I can use?

I would follow the same procedure you have mentioned above, only that before doing that, I would create a safety backup of the email database. This is needed to ensure that the new version of Office 13 won't corrupt it even more. After backing it up, use the procedure you have posted. I don't recommend using a 3rd party application because they're very expensive and there is a big chance it won't work at all.

If you are unable to repair large PST file using scanpst.exe (offered by Microsoft) then you can try third party Outlook PST Repair utility that repair any size of Outlook.pst file.

I used scanpst.exe to fix “Fatal Error: 80040900” in MS Outlook, but I am not able to fix this error using this tool. Instead of scanpst.exe, I found another tool named Outlook PST Repair.

Searching on the web, I found this informative post and thinking for my contribution as well.

Though scanpst.exe (inbox repair tool) is a good solution to repair corrupted PST files. But sometimes, it fails to repair corrupted PST files. In that case, I would suggest you try a third party tool to recover corrupted PST files and export PST files into Office 365, new PST, and Live Exchange server.
