Cant remember email connected to xbox live account

This is a public forum where users help other users. Thus we unfortunately cannot look into your account. Instead I would suggest contacting an EA Advisor by going to https://help.ea.com/contact-us
You will have to write some keywords about your problem, then fill out product, category and platform, press "Find Solutions" and then "I Still Need Help". Then your contact options will appear. If live chat/phone does not appear, it might be closed in your area at the moment and you might consider changing it to: "United States" or something else in the language selector in the bottom for a better result.
