Xbox and Microsoft account allias Gameshare problem

So I am trying to send a friend of mine my xbox login information so he can login in so we can gameshare, the problem is I dont want anyone having access to my email and my email messages because I have confidential information in there. I have tried to
set up an allias account, but the allias account still can access my email and email messages. Is there anyway I can set up my xbox account with a separate email address then my outlook email address. My xbox account is linked to my main outlook email.

Gameshare question

I know that when you gameshare with someone you make their account your home Xbox. But what if I want to Gameshare with two friends? Would I have to keep switching their accounts as home back and forth?

 

Question about gamesharing with a friend who ran out of them?

So I have one gameshare left because I used my other two (i really dont want to go into the story would take to long) and im going to try and gameshare with a friend of mine but the problem is that he doesnt have any gameshares left so can i still log into
my account on his xbox and set it as my home and then get the games on my xbox? or since he doesnt have any gameshares left will it not work?

 

You should never give your account information to anyone else whether you give them an alias email and even if it is a friend. You would be violating the code of conduct by doing so.
