I recently upgraded to Windows 10, and since that upgrade, I cannot send emails from Microsoft Outlook. I often get a pop-up asking for my password, but when I enter the password, it just keeps displaying the pop-up dialog. When I do a send and receive, I get the message
Task 'Home - Sending' reported error (0x800CCC13) : 'Cannot connect to the network. Verify your network connection or modem.'
