How to Repair Outlook 2013-2003
First, you need to determine the type of data file Outlook is using (pst/ost).
You can look in the default location, or use Outlook to help you find it.
- In Windows 8 the default outlook data file location is: C:\Users\*YOURUSERNAME*\AppData\Local\Microsoft\Outlook
- In Windows 7 or Vista, the default Outlook data file location is:
If you do not see the files in the default locations above, you can use Outlook to identify the file location.
- In Outlook, to find out which data file Outlook is using, click on File > Account Settings (in Outlook 2010) or Tools > Account Settings
- Click on the Data Files tab and click on Open File Location or Open Folder for the default profile selected.
- At the top of the windows file browser, select and copy the directory address of that file (folder location, e.g. C:\Users\*YOURUSERNAME*\AppData\Local\Microsoft\Outlook ) and remember the specific file name (e.g. outlook.ost or outlook.pst)
If you are still unable to see the file, you may need to check if it is a hidden file
- To do this find your users folder, right click and select properties.
- Under general, attributes, click hidden, then OK to see any hidden folders or files.
Also make note of the file size, if your Outlook data file is greater than 2GB, then you will first need to run a truncation tool (see additional instructions below)
- Close Outlook
- Now that you know the file type, you need to run the corresponding ScanPST.exe or ScanOST.exe program. If you are using Outlook 2013, run ScanPST.exe. This can be run from C:\Program Files\Microsoft Office 15\root\office15.
- If you are using Outlook 2010, you will always run ScanPST.exe. This file can be run from Windows > Start menu, by browsing to this file folder: C:\Program Files (x86)\Microsoft Office\Office14\SCANPST.EXE (remove the (x86) if running 64-bit Office)
- If you are using Outlook 2007, choose the program C:\Program Files (x86)\Microsoft Office\Office12\SCANOST.EXE (or SCANPST.EXE)
- If you are using Outlook 2003, choose the program C:\Program Files(x86)\Common Files\System\MSMAPI\1033\SCANOST.EXE (or SCANPST.EXE)
- Now enter the complete path and Outlook data file name (from step 1 above)
Click Start. This may take a while to run.
If any errors still exist, run the steps again until no errors appear.
If these options do not work, try uninstalling and reinstalling Office. You can find out how to do that by clicking here
