How can I log into Gamepass PC Beta with my Xbox Live email and not my main Outlook email?

I assume you have 2 seperate accounts, the one with your Xbox Live email, and the outlook email.

If you find that WPAK's advice does not help, then try signing into the windows 10 device (I assume you are on windows 10) with your Xbox Live email
and see if that allows you to sign into the app with the correct account.

Hi there,

usually this should be possible by clicking the Profile icon in the top right of the app and choosing to sign out in the app, after which you try to sign in again with the correct Xbox Live Account.

Let it know if there are any results

Ok tank you just one last question. If i delete the alias of my main account (dad email). my dad can access to outlook? (sorry for my English)

No, if your father's email is a Microsoft one (@live, @outlook, @hotmail) then removing it will delete his account and he wipl have no access to his emails or OneDrive.

We can just move the Xbox account to a another email and let my dad email access to outlook?

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.

P.S. Not sure if it matters but my gamertag is "jflatto" and the email associated with this is my university email address (i.e., edu) and not a live account. This is the same email that I can use to successfully log into xbox live using my PC. I just
can't figure out how to translate this into logging in using my xbox.
