How to Move Office 2021 Licenses to a Microsoft 365 Tenant

Product: Microsoft Office 2021 / Microsoft 365
Device & OS: not provided
Scenario: Consolidating organizational software licenses into a single Microsoft 365 admin tenant for easier management.
Observed behavior: The 30 perpetual Office 2021 licenses are currently tied to an older account and cannot natively merge into the new Microsoft 365 subscription tenant.

Before you start

Verify whether your 30 Office 2021 licenses were purchased as Retail versions (tied to an individual account) or Volume Licenses, as this dictates whether a transfer is possible.

Solution 1Recommended

Manage Volume Licenses via Volume Licensing Service Center

If your organization purchased Volume Licenses, you can manage and reassign them using Microsoft's dedicated volume licensing portals.

Office 2021 Volume Licenses are tied to your organization's enterprise agreement rather than a personal Microsoft account. You can administer these directly from the Microsoft 365 Admin Center or the Volume Licensing Service Center (VLSC).

Log into the Admin Center

Navigate to the Microsoft 365 Admin Center and log in using your organizational admin credentials.

Access Volume Licensing

Go to 'Billing', select 'Your products', and then click on the 'Volume licensing' section to view your organization's perpetual licenses.

Use the VLSC Portal

If you are using the older management portal, log into the Microsoft Volume Licensing Service Center (VLSC) using the original organizational account.

Reassign Licenses

Update your deployment and reassign the product keys or user assignments to align with your new tenant structure, as permitted by your licensing agreement.

Manage Volume Licenses via Volume Licensing Service Center

Transition to Microsoft 365 Admin Center: Microsoft is gradually transitioning VLSC features to the Microsoft 365 Admin Center. Depending on your region, you may be automatically redirected there.

Solution 2

Request a Transfer Exception via Microsoft Support

Retail perpetual licenses are normally non-transferable, but exceptions may apply for organizations in specific regions like the European Economic Area (EEA).

Frequently Asked Questions

Can I upgrade my Office 2021 perpetual licenses to a Microsoft 365 subscription?

No, Office 2021 is a one-time perpetual purchase. It cannot be upgraded to a Microsoft 365 subscription. To use Microsoft 365 features, you must purchase a separate Microsoft 365 subscription.

What happens to the Office 2021 licenses if the old work account is deleted?

If your Office 2021 licenses are retail versions tied to a specific Microsoft account, deleting that account will result in a permanent loss of access to those licenses. Always resolve licensing transfers before closing any accounts.

Can I activate Office 2021 using my new Microsoft 365 tenant credentials?

No. Unless the licenses were properly reassigned via Volume Licensing, Office 2021 requires the original Microsoft account credentials that were used during the initial setup and activation.
