: My Xbox keeps rejecting my new email address
Thank you for taking the time to post this on the Xbox Forums.

Could you please, elaborate a bit more on what you mean by "canceling my email address"

Just to verify, are you unable to sign into your account on your Xbox 360?

Are you able to sign into your account on the Xbox website?

If you are able to do this, it might be worth to
remove your account and then re-add your account.

When you remove your account, make sure that you select the option that reads
Delete Profile Only to make sure you do not lose any data on your account.

Additionally, before you add your profile once more, make sure to restart your console.

Give this a try and let us know if this works for you!

:)
