What solutions can you try to fix the error 0x800ccc67 Outlook error?

Now, we are presenting the most practical solutions you can try to fix the aforesaid error on Outlook. In fact, you don’t have to try all of these solutions at once. Instead, you can try one solution after the other while checking if the error is fixed.

Besides, let’s figure out how to fix the issues like Outlook disconnected or Outlook not receiving emails with ease.

Solution 01: Temporarily disable the firewall/antivirus on your PC

No matter what sort of antivirus program you are using, disable it as the first solution. This is the most basic solution you can try when you see an SMTP-related error. Sometimes, your antivirus can prevent Outlook from accessing SMTP, so disabling it temporarily would fix the Error 0x800ccc67. The steps you should follow to disable the antivirus may differ based on its type. In general, any antivirus program can be disabled with a couple of clicks. So, in the “worst” case, it may take about 10 seconds to disable the antivirus. As a general guide, just right-click on the antivirus program’s icon (on the tray, next to the clock). Then, you will see a popup menu. Find the option that allows you to disable it.

Solution 02: Change the SMTP Port

If disabling antivirus temporarily hasn’t worked for you, let’s switch to the next solution. In this, we should change the SMTP port and see if it works. To do that, you should first find the email settings. In fact, you can simply do a Google search with your email service provider’s name. What you should note down is the port under the term “Outgoing Mail Server.”

After noting down the port, you should change it in the client. Like with the previous method, the steps to change the SMTP Port varies from one email service to another. So, find the settings related to your email service and change the SMTP Port. After that, you should press F9 or just send the message. If it doesn’t go, switch off the router for a minute or two before sending the email again. This method should work for many users. If it doesn’t, you can still keep your hopes alive and move to the next solution.
