Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Dear @William Crew,
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, your Exchange Online (Plan 1) payment method has expired, and you’re unable to access the Admin Center to update the billing details. You’re self‑employed, don’t have another admin, and are concerned about potential email service disruption.
In this situation, your email service will not stop immediately, and you are still the tenant administrator. However, this issue cannot be resolved through the Exchange Admin Center alone. The most effective way to resolve it is to contact the Microsoft Support team. A Microsoft Support agent will collect the case details and escalate it to the Billing team for further review. You can use the following link to find the appropriate contact number: Global Customer Service phone numbers - Microsoft Support
