One of my users upgrade his laptop to Windows 10. The upgrade process was quite streamlined and trouble free.

After the upgrade Outlook not sending anymore. All the mail server settings are correct and the test message is successful too.
The error message he gets is the following:
Task ’email.address@yourdomain.com – Sending’ reported error (0x800CCC13): ‘Cannot connect to the network. Verify your network connection or modem.’
Microsoft is looking into it, but in the meantime to recover from this issue, you must run the Microsoft Windows Resource Checker tool, also known as “System File Checker” or “sfc”. This tool scans and verifies the integrity of all protected system files and replaces incorrect versions with correct versions. Here’s how:
- Right click on the Start button of Windows and choose Command Prompt (Admin), you’ll need to click Yes to allow it to make changes to the computer if needed;
- Then copy and paste or type: sfc /scannow and then hit Enter (note the space between sfc and /);
- Once System File Checker process is finished, reboot the computer.
With sfc /scannow some critical Office files are being put back where they needed to be after upgrading to Windows 10.
