• Outlook stops sending mail after Windows 10 upgrade - Fix

    5th August 2015 | AJPCSol
  • Something that’s cropped up on 2 of my own computers (and a number of others according to the Internet!) in Windows 10, is a problem with Outlook no longer sending mail and giving the following error message:

    Error message: ‘XXXXXXX – Sending’ reported error (0x800CCC13): ‘Cannot connect to the network. Verify your network connection or modem’

    This has happened on my laptop running Outlook 2010 and my PC running Outlook 2013! Everything was working fine and all of a sudden the email stops going.

    The fix for this problem is as follows:

    Run the Microsoft Windows Resource Checker tool, also know as “System File Checker” or “sfc”, which scans and verifies the integrity of all protected system files and replaces incorrect versions with correct versions. To run it,

    1. Type Cmd in the Windows 10 “Search the web and Windows” box
    2. Right click on the Command Prompt (Desktop App) link that appears and choose: Run as administrator
    3. At the prompt type: sfc /scannow
      (note the space in the command)
    4. Wait until the process completes. This usually doesn’t take longer than 20 minutes with a regular hard disk and takes much less when you have a fast SSD drive.
    5. Restart your computer.

    This is the result I got from my own check:
