Cant Access my friends content but he can access mine

To add me and my friend have had a very close friendship and trust each other however we have had a problem with people accessing mine or his account which has been sorted when i locked down my profile and he did the same

If it is content your friend owns, your friend will need to be the one that sorts it out. The reason for this is the Xbox Live Code of Conduct - it states that users are not allowed to access accounts they do not own. Since you would be breaking the Code
of Conduct to sign into your friend's account, and we don't want that, your friend will need to access his account and find out what has gone wrong.

Which sounds nice on the surface, but even best friends get mad at one another from time to time. As choppy pointed out, numerous users who claim to have trusted their friends have had accounts suspended (or even permanently banned) because of something
the other person did out of spite, or because someone else (someone they knew but you didn't) did something.

We get the desire to let others use your games, but the risks associated with letting someone else have access to your account is simply too great.

Also just to add to Randy's post, Not only is sharing account info against the COC it's very very risky, People lose accounts all the time to this, Experience fraud or even get bans unknowingly because the other person was using their account.

I see Thank you both for the replies, i managed to get it working somehow, but This would have been my first post to Xbox about any issues apologies for any inconveniance
