Microsoft is actively working to resolve the issue.
Update: Today’s Xbox One and Xbox Live startup, sign-in, and account issues have been resolved, according to Microsoft.
The official Xbox Live status page notes all services are operating as they normally used.
Original story follows:
Xbox Live is currently experiencing issues preventing Xbox One owners from being able to sign into core Xbox Live services, as well as create, manage, or recover accounts.
Xbox Live’s status page notes there is limited availability of the core Xbox Live service, and as such players may not be able to log in, download updates, or may even be encountering console startup issues.
Xbox’s official support Twitter page has acknowledged the issues, saying “We are aware of reports of Xbox One console startup, title update and sign-in errors. We will keep everyone informed once we have more information to share. Thank you all for your patience.”
The Xbox Live status page also notes the issue, explaining that “Our engineers and developers are actively continuing to work to resolve the issue causing some members to have problems signing in to Xbox Live. Stay tuned, and thanks for your patience.”
