How to change the Microsoft account my Microsoft 365 Family subscription is under

You cannot transfer the existing Microsoft 365 Family subscription from the Gmail-based Microsoft account to the Outlook account, but you can share it with the Outlook account now and make that account the owner after the current subscription expires.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Transfer a Microsoft 365 subscription to another account | Microsoft Support")

Use the subscription with the Outlook account now

1. Open the Microsoft 365 sharing page: https://account.microsoft.com/services/office/sharing
2. Sign in with the Gmail-based Microsoft account that owns the subscription.
3. Select Share.
4. Choose Email invite, enter the Outlook address, and select Invite. Alternatively, create and send a sharing link.
5. Open the invitation while signed in to the Outlook Microsoft account, then select Get started and Join now.
6. From the Outlook account dashboard, install or sign in to Microsoft 365.

The invitation must be accepted within 48 hours. If the Outlook account already belongs to another Microsoft family group, it must leave that group before accepting.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Share your Microsoft 365 subscription | Microsoft Support")

This allows the Outlook account to use the desktop Office apps and its own OneDrive storage. The two Microsoft accounts remain separate—their email and OneDrive files are not merged.^3^ Certain AI features and extended-storage options are owner-only and therefore remain with the Gmail account while it owns the subscription.[^2^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Share your Microsoft 365 subscription | Microsoft Support")

Your Windows sign-in can remain the Outlook account; it does not need to match the account that currently owns and shares the Family subscription.

Make the Outlook account the owner later

1. Sign in to Services & subscriptions with the Gmail-based Microsoft account.
2. Turn off recurring billing for that subscription. If the page shows Turn on recurring billing, it is already scheduled to expire.
3. Continue using and sharing the subscription until its displayed expiration date.
4. After it expires, buy Microsoft 365 Family while signed in with the Outlook account.
5. From the new owner account, send fresh sharing invitations to anyone who still needs access.

Microsoft requires the current subscription period to expire before a different account purchases the replacement and becomes the sharing owner.[^1^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Transfer a Microsoft 365 subscription to another account | Microsoft Support")

If the renewal was very recent

If the subscription was purchased or renewed directly from Microsoft, sign in using the Gmail-based purchasing account, open Services & subscriptions, select Manage, and then Cancel. The cancellation process will automatically indicate whether a refund is available; cancellation does not always produce a refund.[^4^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft subscription refund policy | Microsoft Support")

Only after confirming the cancellation/refund outcome should you purchase the replacement under the Outlook account. Cancellation can reduce storage allowances for the owner and everyone sharing the subscription, so avoid a gap if anyone is using more than the free storage allowance.[^5^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Microsoft 365")

If the renewal was purchased through Amazon, another retailer, Google Play, or Apple, billing and refund requests must be handled by that seller rather than through Microsoft’s cancellation page.[^6^](https://support.microsoft.com/accounts-billing/subscriptions/[Subscription ID] "Unable to cancel your Microsoft subscription | Microsoft Support")
