I accidentally redeemed my Microsoft 365 Family product key on the wrong Microsoft account

Hello, thank you for reaching out to Microsoft Q&A.

Unfortunately, you cannot transfer an Office 365 subscription or perpetual license from one Microsoft account to another. Once a product key is redeemed to a Microsoft account, it is tied to that account. This license or subscription isn’t transferable.

In situations like this, you may need to contact Microsoft Live Chat support directly, as they are the only ones who may be able to help with transferring the license. However, this cannot be guaranteed, and they may only be able to assist under certain conditions. Follow the steps below to get in touch with them:

• Go to this page: https://support.microsoft.com/th-th/home/contact
• Type Talk to an agent, then click Get Help.
• At the bottom of the page, click Contact Support. Sign in to your Microsoft account if needed. If you face the same issue with the affected account, use a different account to contact Microsoft Support.
• Select Office products and then click Confirm.
• Click Chat with a support agent in your web browser.
