Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi @Bonnie,
Thank you for reaching out and sharing the details of what you’re experiencing.
Receiving a message that your email address doesn’t exist - particularly when it has been used for an active, paid Microsoft 365 subscription for an extended period - can be unexpected. The information you’ve provided is helpful and points more toward an account or tenant access issue rather than a problem with billing itself.
To help protect your personal information and ensure accurate assistance, please share your email address with me via Private Message.
Once your message is received privately, I’ll be able to review your case and provide an update as soon as possible.
I look forward to your reply and will be happy to help you further.
Warm regards.
