You will receive the error code 80072ef3, which prevents you from logging in to your Xbox Live account after you have provided your e-mail and password. The problem most commonly occurs due to outdated or corrupted cache files containing old information stored in them. So, if you log in or do something else that the system wants to check the cache for, this error will be displayed.
Clearing the cache contents will usually fix this error. Before you begin, make sure your Xbox can connect to the Internet.
