The user needs to install and activate Microsoft 365 on a new computer but no longer has access to the canceled email address tied to the original subscription.

How to Move Microsoft 365 from an Old Account to a New Computer

Product: Microsoft 365
Device & OS: not provided
Scenario: Transferring an existing Microsoft 365 subscription to a new device using a different Microsoft account.
Observed behavior: The subscription is permanently linked to an inaccessible email address, preventing the user from easily activating the software on the new computer with a new account.

Before you start

Before proceeding, check if you still remember the password for the old Microsoft account or if you have any alternative recovery emails linked to it, as you will need account access to manage the existing license.

Solution 1Recommended

Access the Original Account to Install on the New Computer

If you can still log in to the old Microsoft account despite the email being canceled, you can install and activate Office on your new device.

Even if the email address itself is no longer active (e.g., a closed ISP email), the Microsoft account associated with it might still be accessible if you know the password.

Sign in to Office.com

Navigate to Office.com on your new computer and sign in using the old email address and password associated with the Microsoft 365 subscription.

Download the Office installer

On your Microsoft account dashboard, locate and click the 'Install Office' button to download the setup file.

Install the software

Run the downloaded installer on your new computer and follow the on-screen prompts to complete the installation process.

Activate Microsoft 365

Open any Office application such as Word or Excel, and sign in with your old Microsoft account credentials when prompted to activate the license.

Access the Original Account to Install on the New Computer

Account Management: Once logged in, consider adding a new email alias to your Microsoft account in the account settings so you do not lose access in the future.

Solution 2

Purchase a New Subscription with the New Account

Use this solution if the old Microsoft account is permanently inaccessible and cannot be recovered.

Frequently Asked Questions

Can I transfer my Microsoft 365 subscription to a different email address?

No, Microsoft does not allow you to manually transfer an active Microsoft 365 subscription from one Microsoft account to another. You must continue using the original account, or purchase a new subscription for the new account.

How do I change the email address associated with my Microsoft 365 account?

If you still have access to the account, you can log into your Microsoft account dashboard, navigate to the 'Your info' section, and select 'Edit account info' to add a new email alias. You can then make this new alias your primary email.

What happens if the email provider cancels the address linked to my Microsoft account?

Even if the email address is canceled by the provider, the Microsoft account itself remains active. As long as you know the password, you can still sign in to Office.com to manage your subscription and add a new functional email alias.
