  • Now hit ‘Finish.’ Verify the Outlook settings.


Use Outlook in Safe Mode

The safe mode in Outlook is much like the incognito window in Google Chrome. When you use Outlook in safe mode, it will launch without any add-ins. Thus, you can safely use the email without letting the add-ins interfere with it. 

  • Launch the ‘Run‘ dialog box by pressing the Windows key and R.
  • In the ‘Run‘ box, input ‘Outlook /safe‘ and hit ‘OK.’
  • You will see a ‘Choose Profiles‘ window opening. On it, tap ‘OK.’


Check the Size of Your Router’s MTU

MTU refers to the Maximum Transmission Unit. It is the greatest packet size that can be transmitted over the network without causing any fragmentation. If a packet is greater than the MTU setting, it will split into smaller packets. If there are many of these packets, data transmission over the network drastically slows down. 

Moreover, if you are using the wrong size of MTU, you’ll be unable to open many web browsers. Outlook Error 0x800ccc0f also has a higher chance of occurring since you’ll be unable to transmit or receive files over the network. To resolve this problem, you should check your existing MTU value and find the correct MTU size. You should connect with your internet service provider for the same. You can execute a ping test for your router, like ping –f -11472, and you’ll be able to see the MTU status.


Examine Any Connectivity Problems

It is a basic yet commonly ignored resolution for the error. If you don’t have a stable or good internet connection in the first place, you will find it extremely hard to carry out proper email exchanges. Open any web page and see if it’s displayed properly. If it’s not, it means you need to fix your internet connection by either examining the Ethernet connection or the Wi-Fi signal strength.


Summing Up

The Outlook Error 0x800ccc0f can definitely be very troubling. It hinders email communication while also leaving you confused as to what to do to fix it. Fortunately, there are many fixes you can implement to get rid of it. However, if the error persists, it’s a good idea to call the professionals of an Outlook support service and get the needed help.
