Scenario: Moving a Microsoft Office license from a personal or previous account to a new work account.
Observed behavior: Product keys are linked to the original account used during redemption and cannot be directly reassigned by the user through account settings.

Solution 1Recommended

Contact Microsoft Support for License Reassignment

Because product keys are permanently bound to specific accounts upon redemption, you must contact Microsoft Support directly to request an account transfer.

Office 2016, 2019, and 2021 licenses can generally be transferred to another device owned by the license holder. However, transferring a license to an entirely different account depends heavily on regional laws (such as in the European Economic Area) and specific licensing terms. Community agents cannot change payment or account ownership, so reaching out to official support is mandatory.
