Use the Windows System File Checker to repair corrupted files

  1. Close Outlook.
  2. Right click the Start button in Windows and choose: Command Prompt (Admin). If you don’t see that option, instead choose: Windows PowerShell (Admin).
  • In the Command Prompt window type: sfc /scannow (note the space in the command).
  • Wait until the process completes. This usually doesn’t take longer than 20 minutes with a regular hard disk and takes much shorter when you have a fast SSD drive.
  • Restart your computer and then open Outlook.
