Windows Live Messenger: Unable to Connect Error 80040200 Fix

 

I stumbled across this fix via a web search in the Live Messenger Blog about a different error code. It worked for me on Windows Vista.

1.) Close Messenger. Go into Task Manager and ensure that the “msnmsgr.exe” process is not there. If it is, kill the process.

2.) Navigate to C:\Users\<YourUserName>\AppData\Local\Microsoft\Windows Live Contacts and delete the entire contents of the folder.

3.) Restart Windows Live Messenger. Voila!

There is another issue I found where the standalone installer for Messenger fails with a message like “could not open key…”. One fix for this is to navigate to the C:\Program Files\Windows Live\Messenger folder and DELETE the msnmsgr.exe executable if it is there.

I think it was Donn Felker who first tweeted about this, but I didn’t believe it until I got one myself:

  4. @Bill,
    There is a contacts.edb contacts database that can get corrupted. By deleting all this, you are forcing Messenger to regenerate this data fresh.

  5. BTW, I neglected to point out that I've done this fix three times now. After deleting (as per the instructions), Windows Live Mess. works fine for about a day.

    I am certainly not going to apply this fix every day... so unless MS fixes this, I will need to revert back to the older Messenger.

    You can just restart MSN and it works I was afraid all my settings would go so I just restarted it and it worked.

  8. Does anyone know WHY this is occurring?

    I never had a problem until I upgraded to this version of Messenger. Peter's 'fix' does work, however, it is temporary. It seems that Messenger fails every few days. I can restart it but it is only a matter of time before it fails again!

    Microsoft's support doesn't even acknowledge that this is a common issue!

    Anyone?

  19. Please check you system datetime. For some reason my system datetime was set in 2 months ahead(I have young twins so I am not surprized). But Peters fix didn't work for me. I did go on that folder and deleted the file. When I tried to log in, I was getting the error and that's when I noticed the "date" . I fixed the date on the system and it logged in just fine.

  21. Read Item #2 in the post. "YourUserName" is the name of your user profile on the machine.

  27. I tried for 3 months to get my messenger to work. I tried every solution. It went from a messed up error code to the 80040200 error code. I tried what you said and the first thing out of my mouth was no fricking way... it worked!!! I am very impressed... thank you! Your solution was very quick and effective!
