We have had many customers reporting Outlook Error Ox800CCC13 after upgrading to Windows 10. The solution is to run sfc /scannow from an elevated command prompt to resolve the issue –
1. Right click on the start button
2. Select ‘Command Prompt (Admin)’
3. In the window that appears enter – sfc /scannow
4. Wait for the System file checker to complete and then restart the computer.
