Scanpst (aka the Inbox Repair tool) is found in your Office installation folders, usually C:\Program Files\Microsoft Office\OfficeXX, where XX is your version of Office. In Vista and Windows 7 64-bit, the folder is C:\Program Files (x86)\Microsoft Office\OfficeXX.
Note: The scanpst icon is a broken envelope. This is supposed to indicate that it works with broken messages. It does not mean the application is broken.
C:\Program Files\Microsoft Office 15\root\office15\scanpst.exe
C:\Program Files\Microsoft Office 16\root\office16\scanpst.exe
Office 2010 Home & Business 'Click to Run' users: With Click to Run, Office is installed in a virtual space on the Q drive and you need to look for the path on the Q drive. If you aren't sure if you are using Click to Run, check File, Help in any Office 2010 application. More info on Click to Run is here.
To find the path on the Q drive, open Word and open the File, Save as dialog, choose 'all files' in the file type dialog and browse to Q:\<14####.lan>\Office14. Copy the Q path and paste it into the address bar of windows explorer.
Replace XX in the following to match your version (the textboxes below are editable), then copy and paste it into the Address bar of Windows Explorer and press enter to open ScanPST.
| Outlook 2016 = 16 Outlook 2013 = 15 Outlook 2010 = 14 Outlook 2007 = 12 Outlook 2003 = 11 Outlook 2002 = 10 Outlook 2000 = 9 | If you are unsure of your version Help, About will list the version in '12.6310.5000' format. If Outlook was installed as part of a suite, Help, About in any of the Office programs will have the correct version number. |

Using Scanpst.exe
After scanpst opens, click Browse and browse to the location of the PST. Or paste the following line in the File name field and click Open. This will open the default PST location in the file browser.
%USERPROFILE%\Local Settings\Application Data\Microsoft\Outlook
This path works in all versions of Windows if Outlook created the pst in the local application data path. If you moved the pst or Outlook 2010 created the pst file in My Documents, you'll need to click Browse.
Select your PST from the list (most people will have just one) click Open, then Start to begin testing the PST
When ScanPST is finished running the tests, a dialog reports the errors found. If you need to repair the PST, always make a backup.

Love this website, gave me a link to access my on board tool
Hi I have down loaded Stellar Phoenix Outlook PST Repair. I have run this on my pc but it seems to get to a point and do not move further. I have left pc on overnight and still at same point. How now from here. Thanks Denise
if its stuck, I'm guessing the pst is beyond repair.
I ran scanpst. My file is very large, about 15 gig. It worked for about 3 hours, progressing through all the stages and then at the end I got the following error: Offline Synchronization is not supported by your mailbox. I am using Windows 7 Ultimate and Office Professional 2007. Any help you can provide is much appreciated.
What type of email account do you have configured? Is this an ost file or a pst file?
Are you using scanost or scanpst?
ERROR: "Offline synchronization is not supported for your mailbox."
CAUSE: Your default profile does not have an information service set up for Microsoft Exchange Server. Select a profile that includes Microsoft Exchange Server.
I am trying to run scanpst.ee on all my pst files - its gonna take a while I guess to scan 33 gb size of pst files.
Has anyone faced this weird occurrence before - my outlook opens up , is ok for first few minutes, then it goes into a sweet cherishing "no responding" mode, up the CPU cycles, eventually hangs my machine. And the only option I have is to hard boot machine everytime.
How many pst files do you have?
Does it work in Safe mode?
I would go into Control panel, mail and set a new, empty pst as the default, maybe remove the large pst files from the profile and see if it works better. At least you'll be able to use Outlook while scanpst runs on the pst.
This problem is weird. Outlook hangs and then in turns hangs my machine
The hang is probably due to the size of the pst.
