Forgotten Outlook email address for one of my old Xbox accounts.

Problem solved! I found thatI I have an old ms account attached to an old email address that I had forgotten all about. My gamer tag is linked to that one, so all good.

It sounds to me like you have also forgotten your original email address. If you created a new account with the same email address as your old account, it would have told you to use a different email address because your old one is still active. Do you
have that original profile on your xbox console? If so double check the email address, Settings>Account>Your Information. That email address is tied to your original gamertag and has to be used to recover that gamertag and all gaming info.

Yes. That's what happened. So now I have 2 additional outlook emails that were set as primaries and my original emails were removed. One of the new outlook primaries logs me into my guest account. The other new outlook email takes me to a new xbox account that I've never used before. And neither of the other email addresses work. So I can't get into my main account.

I've actually had a random gamertag (Xbox LIVE account) associated to a Hotmail/Outlook LIVE email address when I created it.

Surely you should be able to log into the new account that was created when you created the new Outlook email address.

Change the email address associated with that new account, freeing up the new Outlook email address that you created.

Change the email address of your CURRENT Xbox LIVE ID to that new Outlook email address. Doing all that while on the computer, should still have that same Outlook email assigned to your phone, ON your phone. I don't have a Windows phone but that's basically
what I had to do when it messed up on my new Windows 8 laptop.

.

However, with the new local currency that Microsoft has switched to, changing the LIVE ID associated with a gamertag MIGHT remove all remaining funds off the account.

the account connected to my old gamertag is a microsoft account, but it doesn't have @outlook or @hotmail) and the new email account that I want to be connected to my old gamertag is also a microsoft account but @gmail, not @outlook or @hotmail
