problem with the security of my account

You may have a problem with Account security proofs if your Xbox connects to net but you can't sign into XBLive.

Yes. This is, BTW, a Microsoft Account issue, not an Xbox issue; the Microsoft Account support folk have their own support forum at

http://windows.microsoft.com/windows-live/id-help-center

0) If you already have a second Microsoft Account (formerly known as the Windows Live ID) you can skip step 1 altogether

1) Make a new Microsoft Account at
http://startup.live.com which after you complete it should lead you to the Account Summary

1A) If you don't get to the Account Summary page, go to
http://Account.Live.Com and sign in there.

1B) If you are prompted to cofirm the email address, please do so.

2) Complete the security information by clicking on the Edit Security Info link below. Make sure to add the Security Question down below as well as a cellular number in the Phone Numbers field and an alternate email address which is different from the Microsoft
Account address.

3) Then, enter
http://go.microsoft.com/fwlink/?LinkID=242792 in the address bar of your browser. Fill in the form there, with the subject EMAIL BEHIND MICROSOFT ID IS BROKEN - give a good working email where their support folks can find you. You should receive a response
within a day, the gods willing.

Ah, OK, to clarify- are you seeing the error message just on your account, just on their accounts, or on both? If it's just on their accounts, then can you please try to open that link in a private browsing window and have one of the affected accounts be
the one to log in. If it's just your account, then can you please try clearing your console's cache three times, and restarting the console before you try redownloading again. Let's see if either of those clear this up.

Soryy Mis Ermine, but at the moment I do not understand anything what you wrote at the moment. Just to clarify I start again from beginning.

problem description step by step:

1. My Xbox Live account is
2. When I log in with MY ACCOUNT, then let's say after every second log in (not everytime) I see window what suggest to me add security proofs.
   
3. The message in window show my e-mail and asking do I get messages to this e-mail?
   
4. So after YES, next message suggesting add another security proofs.
5. Okay no problem. So I chose TEXT (SMS) and I add my phone number.
6. After that appears ERROR message:
   
   "Thanks! You added this earlier, but we can't use it until you verify it at https://account.live.com/p
   
   While you're there, it's good idea to check the others on your account, too.
   
   Code: 80049C0B"
7. Okay, I go to my laptop.
8. Open browser (Chrome or Internet explorer, there is no difference)
9. Add this URL from error message https://account.live.com/p
10. I log in with my account
11. Window that opens does not contain any information about how to I suppose verify my number.
    
12. But my number (also e-mail, and PC) exist "password and security info" area. I do not know what it means. Does it mean that my phone number is already added to my account (and verified?) and I can use it in future to retrieve my password or whatever? Or
    not?
13. So because there is nothing to do on that page I go back to Xbox 360 Elite console and I try again. Same error message (look number 6).
    
14. So it looks I can't add and verify that number for Xbox Live. So I cancel AGAIN!
    

Mister Cerb suggested one solution how to fix that problem (scroll up 2-3 post).
He suggested to delete my account from Xbox 360 and then clear system cache 3 times. I tried it. Deleted my profile () from Xbox 360 console. And then I cleared system cache 3 times. Power off. Power on. Downloaded my profile.

And I am back in beginning! Nothing changed! Same error message all the time:

"Thanks! You added this earlier, but we can't use it until you verify it at https://account.live.com/p

While you're there, it's good idea to check the others on your account, too.

Code: 80049C0B"

And now some curiosity, maybe there is some sort of problem too. I do not know how this system is built up. But because there in webpage (https://account.live.com/p ) is options:

• Manage linked accounts
• Manage parental permissions

When I choose "Manage parental permissions" I get message: "You have no child accounts."

? ? ?

How i'ts possible? For both my sons accounts are set my account () to parental account. And on Xbox 360, when they need something from Xbox Live it's always asking my approval (my account e-mail and my account password). Working! I am using it every
week. So I am little bit confused now why same time this account system says that I do not have child accounts?

Sorry it's a best what I can do to describe my problem(s)!

This message keeps popping up every time i add security for my xbox proofs. I add all the info i press done and this error pops up CODE:80151103
