I recently found a few client phoning me explaining, they cant send emails from outlook even though on the account settings screen the “Test Account Settings” test delivers successful results.
The Message Office gives is something similar to cant connect to server. All of the clients had one thing in common, they recently upgraded to Windows 10. Well luckily there has been oen fix that proved successful every time so far.
On the PC open a Command Prompt window, this can be done by clicking on the search icon and type “CMD”. From the results you are given right click the “Command Prompt” item and click on “Run as Administrator”.
A new window opens ( with a black background ). in this window type “sfc /scannow”.
Leave it to finish and thats it. Close your Outlook and open it again.
Should be working.
