Outlook can’t send after upgrading to Windows 10

Outlook can’t send after upgrading to Windows 10

I just had a customer upgrade to Windows 10 and he complained that Outlook can’t send messages anymore.
We verified all the mail server settings were correct and interestingly enough, the test message sent successfully. The error message:

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

Be aware on the Internet there are numerous supposed fixes relating to the same error and ask you to fix your exchange server 2010 with a service pack. This is a different issue so do not get confused. This Fix applies to errors after upgrading to Windows 10.

This is how I fixed it:

Run the Microsoft Windows Resource Checker tool, aka “System File Checker” or “sfc”.
This tool scans and verifies the integrity of all protected system files and repairs or replaces corrupt files after the upgrade.

  • In the search bar next to the new Windows 10 new START button Type CMD
  • You will then see the option CMD Command Propt – Desktop app highlighted.
  • Right Click on this option and select “Run as administrator”
  • If you have User Account Control activated click “Yes” to run the program
  • You will then be faced with command prompt: C:\WINDOWS\system32>
  • At the prompt type: sfc /scannow
  • Wait until this completes. This usually will take about 8 to 20 minutes depending
  • on your system configuration and disk drive.
  • NB: Shutdown your Computer (Do not just put it into sleep mode or simply log out)
  • Restart your computer.

Test sending email messages again using Outlook, it should work.
Hope this helps you; If not, please call me to make an appointment.
