How to Manage a Microsoft 365 Account After a Subscriber Dies

Product: Microsoft 365
Device & OS: not provided
Scenario: A Microsoft 365 subscriber or subscription owner has passed away, and the organization must secure their data and manage the ongoing license without losing administrative access.
Observed behavior: The organization must preserve the deceased user's emails and files, transfer administrative roles, and reassign or cancel the license securely.

Before you start

Ensure you have global administrator privileges for your organization's Microsoft 365 tenant, and gather any necessary legal documentation proving organizational ownership in case you need to contact Microsoft Support.

Solution 1Recommended

Secure the Account and Transfer Data via Microsoft 365 Admin Center

Use this method if you already have administrative access to the Microsoft 365 tenant to preserve files and reassign licenses.

If you are an authorized administrator, you can manage the deceased employee's account directly through the Microsoft 365 Admin Center. This allows you to secure company data, reallocate licenses, and maintain business continuity.

Block sign-in access

Log in to the Microsoft 365 Admin Center using a global administrator account. Navigate to 'Users' > 'Active users', select the deceased user, and click 'Block sign-in' to prevent unauthorized access.

Preserve mailbox data

Convert the user's mailbox to a shared mailbox or grant another user delegation rights under the 'Mail' tab. This ensures important organizational emails are preserved and accessible.

Secure OneDrive files

Go to the 'OneDrive' tab for the user and generate a link to their files. Transfer the ownership or back up the required documents to a shared repository or a replacement employee's account.

Reassign or remove the license

Once all data is secured, go to the 'Licenses and apps' tab, uncheck the assigned license, and save changes. You can now assign this license to a new user or remove it from your billing to save costs.

Secure the Account and Transfer Data via Microsoft 365 Admin Center

Data Retention Notice: Make sure to back up or transfer OneDrive and email data before fully deleting the user account, as deleted user data is typically only recoverable for 30 days.

Solution 2

Contact Microsoft Support for Lost Administrator Access

If the deceased person was the sole global administrator, you must contact Microsoft Support to regain access to the tenant.

Frequently Asked Questions

Can I access the personal OneDrive files of a deceased employee?

Yes, if you are a Global Administrator for the organization's Microsoft 365 tenant, you can grant yourself or another user access to the deceased user's OneDrive through the Microsoft 365 Admin Center before deleting the account.

How long is the data kept after removing a Microsoft 365 license?

Once a license is removed from an account, the user's data (such as Exchange emails and SharePoint/OneDrive files) is typically retained for 30 days. After this period, the data is permanently deleted unless preserved.

What happens if the deceased person was the billing owner?

You will need to update the billing information and payment methods in the Microsoft 365 Admin Center under the Billing section. If you lack admin access to do this, you must contact Microsoft Business Support with proof of business ownership to resolve billing control.
