We came across another Outlook “funny” today at a Client’s who had recently upgraded to Windows 10. Since the upgrade no emails have been sending and they were getting the error “8x800ccc13 cannot connect to the network verify your network connection or modem”, which is working of course as they were online. Outlook 2013 won’t send emails after Windows 10 upgrade – we’ve not seen this before so it took us an hour or so to work out how to resolve it.

The fix for Outlook won’t send emails after Windows 10 upgrade:

Click on the search icon, search for “cmd” when you find the application (Command Prompt) run as administrator (i.e. right click it and click run as administrator). You will then see a rectangular black window appear with folder> then type in sfc/scannow and sit back and wait (takes a while to run).

When finished type in exit. Then close outlook, restart and problem solved.
