Outlook can’t send emails after Windows 10 upgrade

A few people have reported that Microsoft Outlook 2007 onwards will not send emails after they have upgraded to Windows 10, the good new is there is a really simple solution to fix it:

If you’re not familiar System File Checker is a scan that will scan your Windows 10 for any corrupted system files, and it will repair those files if possible.

To perform System File Checker scan you need to do the following:

  1. Right click on the Start button and click on Command Prompt (Admin). If for some reason Command Prompt isn’t available you can choose Windows PowerShell(Admin) instead.
  2. When the Command Prompt opens you need to type sfc /scannow. (note the space in the command)
  3. Press Enter and wait for the process to complete. System File Checker can take about 20 minutes on a regular hard drive, so make sure that you don’t interrupt it.
  4. When the scan finishes it will inform you whether it was successful or not.
  5. Restart your computer and check if the problem is solved.

      Hi Chrys, Sorry to hear you’re still having problems. That fix has tested working on the two or three workstations that we have encountered the problem on. If it’s not working for you then I suggest checking the official Microsoft forums and seeing if anyone else is having a similar issue
