Hi,

No you can't download them from your new account. The old one allows you to play to the contents you already bought on the xbox but not to use the rights of your old accound on the new.

For the online part, I think It should work fine.

in short old xbox live account lost, still want same Facebook on new account, can't access old xbox account to unlink, and Facebook doesn't show my Facebook as connected but when I try connecting Facebook to new account it says it's logged in to the old
account.

If you do know the old email (even if it isn't existing anymore), you can try to log into that Microsoft Account. If it's a third party email (like Gmail, Yahoo or your old work or school email), the email is just a username string that looks like your old
email. It is actually a separate account, so even if your old email doesn't exist, you should be able to sign in.

HOWEVER: Microsoft also checks some security questions and might send a confirmation code to that old non-existent email. So if you didn't have any backup like a secondary email or a phone number to text you the code, you might not be able to sign in to
that account.

If you were able to sign into that old account, make sure that you add recovery emails and phone numbers at

As for combining your two accounts: You can't combine two Microsoft Accounts. If your new account has NOT made purchases or doesn't have important data, you could delete your new Microsoft Account, sign into the old Microsoft Account, and create a new Alias
using the deleted new Microsoft Account information. Make your new Microsoft Account address the Primary Sign in Alias, and you should be golden.

However, if you have made purchases on the new account, you can't take them with you. So you'll have to decide which is more important for you.

Hello

I am thinking that it is more an account problem than the game since the old email account I had, I do not have access to it anymore and it tells me that that account doesn't exist when trying to log in, note that I changed the name of that email and I have recovered it but I put the changed name to the new primary domain and deleted the old one, that's when I stopped receiving emails so I close that account. however, I don't know what i did when i tried to sign into halo that i get that error and said that the old account doesn't exist, tried to create a new one with the same name as the old accounts but it tells me that its in use. So I don't know what to do. Is there a way that Microsoft can delete those old emails from their servers?
