• Click OK.

Deactivate the Windows Firewall and Antivirus Software

Windows Firewall can block MS Outlook if it is using any third-party plugins. Thus, deactivating the firewall can be a feasible solution to fix Outlook error 0x800ccc0f.

Recommended: Instead of disabling the firewall you can set the adequate priority with MS Outlook and Express email client in Windows Firewall. Allow the access for the following two files:

• Outlook.exe (in MS Outlook)
• Msimn.exe (in Outlook Express)

Steps to disable the Windows Firewall: 

• Go to Start and then go to the Control Panel.       
• Select System and Security.
• Then click on Windows Firewall. 
• Click on Turn Windows Firewall on and off.
• Then click on the last option of Turn Off Windows Firewall. Click OK.

NOTE: Deactivating Windows Firewall can make your device vulnerable to unauthorized access.

After you have disabled the Windows Firewall, you have to manually add the SMTP server name for outgoing emails. You also have to add the POP3 server name for incoming emails to the Outlook account.

Steps to do so in Office 2016, 2019:

• Go to MS Outlook and click on File. 
• Then select Account Settings.
• Select the email account and click on Change.
• Type your server’s name in the Outgoing mail server (SMTP) section and click on Add>POP3>Next. 
• Fill in the correct POP3 mail server details and click on Next.
• Click on More Settings> Outgoing Server.
•  Enter the Username and password.
• Click on OK>Next>Finish. 

Any third party Antivirus software that scans emails can restrict Outlook’s outgoing and incoming emails. So turning off the Antivirus Software can fix the Outlook error 0x800ccc0f.

Recommended: Instead of disabling the Antivirus, you can just try to enable error-free compatibility between antivirus and MS Outlook. The guidelines to make Outlook compatible with your Antivirus software you can refer to the respective antivirus software’s website.

Otherwise, you can provisionally disable the antivirus from Windows and then restart the OS as follows:

• Right-click on Windows 10 taskbar and then click on Task Manager.
• Select Task Manager> Start-up tab. 
• Click on Anti-virus utility> Click on Disable. 
• Reboot Windows.

If this hack is also not able to remove the error then proceed with the next step. 

Check if there are any faulty Outlook settings

Faulty Outlook settings can lead to Outlook sending receiving error 0x800ccc0f. For example, the wrong SMTP host, incorrect username or password, authentication, SMT ports, etc. can affect the Outlook profile.

So check the default profile settings of the Outlook account. In case you do not know how to rectify it, create a new profile after deleting the previous one. ( Creation of a new Outlook profile will not be applicable for Outlook Express). This step can fix the issue if there is an Outlook profile corruption.

{Optional}You can also try to repair the Outlook profile corruption with the following steps:

• Open MS Outlook and click on File
• Click on Account Settings and again in the dropdown list click on Account Settings. 
• In the next window select the corrupt Outlook profile from the options and hit the Repair button. 



• Confirm the login details and hit Next.

Changing the wrong Outlook settings should resolve the issue but if not, then the cause of the error is OST/PST file corruption.
