Close account due to death

To cancel a deceased person’s Microsoft subscription or account when sign-in details are not available, only the following actions are supported:

1. If account credentials are known (email + password and any required verification):
   • Follow the documented steps in How to close your Microsoft account to close the account. After closure, the account can be reopened within 60 days by signing in again; after 60 days it and its data are permanently deleted.
2. If account credentials are not known (cannot sign in, no phone attached, etc.):
   • Microsoft cannot provide access or make account changes based solely on name, address, or email due to privacy and legal requirements.
   • Ensure any subscriptions are stopped via the bank or card issuer instead: close the bank account or card, revoke authorizations, or instruct the bank/credit-card company to block or dispute further Microsoft charges. This is explicitly documented as the supported way to stop billing when the account cannot be accessed.
   • The Outlook.com/OneDrive/Microsoft account itself will automatically expire after inactivity:
     • Outlook.com and OneDrive are frozen after 1 year of inactivity and data is deleted shortly after.
     • The Microsoft account expires after 2 years of inactivity.
3. If access to the deceased person’s data (email, OneDrive, etc.) is required rather than just stopping billing:
   • A formal legal process is required. Microsoft must be served with a valid non‑criminal subpoena or court order on Microsoft’s registered agent in the relevant state/region before it can even consider releasing content from a deceased or incapacitated user’s personal Microsoft account (including Outlook.com, OneDrive, and other Microsoft account data).
   • Sending such legal process does not guarantee that content will be provided; Microsoft will decide after reviewing applicable laws.

Given the situation described (no account number, no phone on file, cannot sign in), the practical steps are:

• Work with the bank or card issuer that is paying the Microsoft renewal to stop or revoke the recurring payment.
• If access to the account’s contents is needed, consult legal counsel about obtaining and serving the appropriate subpoena or court order as described in Microsoft’s guidance.
