Just a quick post on how to scan PST (or OST’s) files if they become corrupt or wont open:
The tool I’ll use is ScanPST.exe which is installed when you install Office 2010.
ScanPST.exe is located below with Office 2010:
C:\Program Files (x86)\Microsoft Office\Office14\SCANPST.EXE
Open the tool and click Browse and find the PST you want to scan:
Then click Start, if the PST is large this can take a while:
If the PST can be fixed ScanPST will prompt you to backup it up before it attempts to fix it:
That’s it done. Try and open the PST or OST again from Outlook.
If the above didn’t work and I wouldnt be surprised if it doesn’t you could try Stella Phoenix PST report tool which is better and generally works!!
