Subscription moves between different email accounts are not covered in the provided material, and the steps to change the Microsoft account associated with an existing Microsoft 365 Home/Personal subscription are not documented here.
However, the context does provide ways to manage and get help with a Microsoft 365 subscription and to contact support, which is required for account- and billing-specific changes like the ones described.
For this situation, the supported path is:
- Sign in with the Microsoft account that currently owns the subscription and check/manage it:
- Go to the Services & subscriptions page and sign in with the Outlook address that the subscription is currently tied to.
- Select Manage for the Microsoft 365 subscription to see where and how it was purchased and what self-service options are available.
- If the subscription was purchased through Microsoft and self-service does not cover what is needed (for example, changing the account that owns the subscription or adjusting invoice details), contact Microsoft support directly:
- Use the Account & Billing Help and Contact – Microsoft Support flows to reach a billing/support agent.
- From there, request help with:
- Whether the subscription can be moved to a different Microsoft account (and what options exist if not).
- Updating billing details/invoice information for the subscription.
- If the subscription was purchased through a third-party retailer (shown when selecting Manage on the Services & subscriptions page), billing and invoice changes must be handled with that retailer’s support, as described in the documentation.
Because the ability to move a subscription from one account to another, or to a Gmail identity, depends on back-end account rules and support policies that are not documented in the provided context, these actions must be confirmed and, if possible, performed by Microsoft support.
