And if you and the freeware client in question go back a long way, we do rejoice over your happy relationship. That is why we do not want Windows Live Mail Error ID 0x800ccc0f to cast a shadow on it. In that light, let’s deal with this issue straightaway.

So, you get the following error message: ‘Unable to send or receive messages for the [your account name]. Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity.’ In fact, this problem can be brought about by a variety of factors, so we recommend you to try each of the solutions below in order to address all of its possible causes.

“All stable processes we shall predict.
All unstable processes we shall control.”
John von Neumann

Here are our top 10 tips on how to fix Windows Live Mail Error ID 0x800ccc0f:

1. Change the Ports

The first fix in line involves tweaking your port settings. To begin with, try changing your port to 995. Make sure SSL is ticked. Besides, set your port for outgoing mail to 465 and enable SSL as well. Now check if your issue has been resolved.

2. Temporarily Disable Your Third-Party Antivirus Solution

Second, you should turn off your third-party antivirus, as it might be in conflict with your Windows Live Mail client. If this manipulation has fixed your problem, you should report the issue to your manufacturer or switch to another antivirus solution.

3. Scan Your PC for Malware

If disabling your non-Microsoft antivirus program has been to no avail, use it to run a full scan of your system.

You can also use Windows Defender for this purpose:

In Win 10:

  1. Start -> Settings -> Update & Security
  2. Windows Defender -> Open Windows Defender -> Full
Windows Defender comes as part of your OS and keeps it safe

In Win 8/8.1:

  1. Start menu – > Type Windows Defender into the Search box-> Windows Defender
  2. Update -> Home -> Scan Options -> Full -> Scan now

In Win 7:

Start -> Type Defender into the Search box -> Windows Defender -> Scan

PRO TIP
Keep in mind that neither Windows Defender nor your third-party antivirus can purge your system of all the hostile enemies – there is always a risk of some treacherous intruder laying low. In this regard, we strongly advise you to use a special program such as Auslogics Anti-Malware to make sure your PC is rid of all traces of infection.
Scan your system to make sure there is no malware lurking around
