2. Run System File Checker scan

SFC scan

  1. Right-click on the Start button and click on Command Prompt (Admin). If for some reason Command Prompt isn’t available, you can choose Windows PowerShell (Admin) instead.
  2. When the Command Prompt opens you need to type sfc /scannow.
  3. Press Enter and wait for the process to complete. System File Checker can take about 20 minutes on a regular hard drive, so make sure that you do n0t interrupt it.
  4. When the scan finishes it will inform you whether it was successful or not.
  5. Restart your computer and check if the problem is solved.

If you’re not familiar System File Checker is a scan that will scan your Windows 10 for any corrupted system files, and it will repair those files if possible.

To perform a System File Checker scan, complete the above steps.

Reinstalling Outlook might also help. If you’re not sure how to do this, ask someone to help you out, or hire someone to do it for you.
