Windows Live Mail Error 0x8DE20003 or Server Error 3204


  1. Thank you so much for your solution.
    It’s working again after 1 week trouble with my mail server error 3204!
    God bless you!

  2. I still have the problem.
    I cannot receive mails because of the error I have since I download Windows 10 (Windows 7>Windows 10).

  3. I upgraded to Windows 10 and I still had the problem after applying the fix. What solved it for me was using my smartphone to open Outlook online and adding each of my accounts, one-by-one. I didn’t know it would work, but each time I added an account through Outlook online on my phone, my desktop Windows Essentials emails would come alive again! I hope this helps someone else as well. Just make sure you know the passwords if you have multiple accounts.
