I am running Windows 10 on a 64bit PC with Windows Live Mail for email. I keep getting the error message "The server has unexpectedly terminated the connection." I have checked with my internet host who tells me the server
doesn't generate messages, so it must come from Windows/Microsoft. How do I prevent it?
I understand you get a Windows Live Mail Error ID 0x800ccc0e, this implies that the application cannot connect to your e-mail provider’s e-mail server. The issue may occur if your server has blocked port 25.
On the problematic PC side, type CMD in the box and then click OK. At the command prompt, type in the following line:
telnet smtpmailserver.domain.com 25.
Also try changing the SMTP port to 587 instead of 25 for the account and check if the issue persists. You can check the setting by going to File > Options > Email Account > (Select_Your_Account) > Properties > Advanced.
If it doesn't work, as the issue is more specific with Windows live mail side, we can ask a question in the following forum to get more help:
