Unable to send email from Microsoft Outlook "Outlook Error 0x800CCC13 Cannot connect to the network"

Also when you test your account settings it all tests fine and you also get the Outlook test message without problem.

But sending new emails or replying to emails it does not send and returns the error above.

We have been seeing this with customers who have Windows 8.1 and 10, This is a problem with corrupt files on your PC/Laptop.

To check and resolve this issue please first close Outlook and all other open programs and make a backup of any important data.

Next you need to open a command prompt as an administrator, you do this by pressing your Windows key and then typing command.

All being well you should see

Command Prompt - Desktop App

Now right click the words "Command Prompt" and left click "Run as administrator"

In the command prompt window that opens type the following command

SFC /scannow

And press return

Let it run until complete which may take a little while, once it finishes it should advise it has found some problems and resolved them.

Now open Outlook and try to send your email again.

All being well this should resolve the corrupted files on your pc/laptop that are causing this issue.

On some occasions if the above does not work you may need to type the following in a command prompt (run as administrator as above)

sfc /scannow

And press return

You may according to Microsoft have to run this up to 3 times, once you have done Microsoft recommend running SFC again.

So again open a command prompt as an administrator and type the following command

SFC /scannow

And press return.

After this your problem should be resolved.
