I need help please

I have a friend who is receiving a error authorizing user coming up on halo 5 what can he do

You might want to go more into detail, and you should likely go to the 343 support forum for this.

Assuming u have looked it up on google and YouTube and Found nothing try loging in to his or her account and see if halo 5 works on your Xbox. Also if he or she has halo 5 on an external storage the check if it is overheating. After that I don’t know what to tell you

Hard reset the Xbox, and check your internet settings.
