"Your iCloud account settings are out-of-date" notification keeps popping up on my Windows 10 PC.

okay, just go to http://appleid.apple.com and log in. There, under the 'Security' section, you will find App-Specific Passwords. Click on 'Generate Password...' and name the app you're going to use. I'd suggest Windows 10. Then you get a set of random letters. Go to your Windows accounts and click on 'Fix account' and enter this newly generated password as your iCloud password. I had no idea that this was a thing until just now.

I am not using the two-factor authentication. I get the settings are out-of-date error message when opening the calendar app on my surface book. When I click 'fix' I enter my Apple ID and PW and the error message pops up again and is never fixed. HELP PLEASE!

AGAIN: The two-factor authentication method did NOT resolve this for me. I have already gone through these steps multiple times. It is NOT HELPFUL to repeatedly suggest the same resolution over and over again when people clearly state that performing these steps has not helped or resolved the problem.

I did the two stage authentication and generated a new password and all worked well until suddenly it popped up again and couldn't get my mail (I hadn't change my Apple password which I know means you need to regenerate). Revoked all app specific passwords and generated a new one.. which worked for half an hour this morning allowed me to download my mail and then the notification popped up yet again and can't get my mail. Using Windows 10 mail ... any ideas?

Great explanation! None of that made sense until I read yours. The 16 digit unknown password was driving me crazy until I saw the App specifc password was 16 characters long. I dont know why there is more notice or instructions from Apple on this. Thanks again

Yes, me too. I followed the directions to create the two-factor password, but it soon comes with the same "out of date" warning. I guess no one has figured this out yet. However, I just sent an email to a friend and it still works even with the error.

This change was made almost 2 months ago and details are available via dozens if not 100s of conversations here and elsewhere.

The delay is likely due to you making other changes to your Apple ID just prior to asking for 2SV.

Please read the previous posts.

And I was always able to retrieve my iCloud mail for 2 years using this computer from Win 8 to 10. My mail just stopped working last month July. I have a regular account that’s not Two Factor Authentication. Why can’t I sign in now? Or is it forcing me to setup Two Factor on the account?

As of June 15th, all 3rd party apps needing iCloud access must use an app specific password.

Which needs either Apple's 2 Step Verification or 2 Factor Authentication enabled on the Apple ID.

I don’t want to use that feature if that’s the case and it’s not fair iif I’m being forced to add it.

Yea, but except I'm still dealing with the same error message, and I HAVE two-factor authentication already enabled, and it has not resolved the problem.

The two-factor authentication method did NOT resolve this for me. Please advise.

So how do I fix the iCloud account so I will stop getting this me

Does this step have to be done on a desktop?

there’s where it pops up.

I've done this. It works for a short time then same issue again.

I just finished an extensive chat session with a Microsoft technician, and the conclusion was that it wasn't a problem with the Microsoft server or Windows 10, but appears to be something on the Apple iCloud server side.
