Maira Mehtab Sep 22, 2026 869 views

Question details

The user wants to know if they can connect or transfer an existing Microsoft 365 Personal subscription, originally set up with a Gmail address, to a newly created Outlook.com account.

Product: Microsoft 365
Device & OS: not provided
Scenario: Managing Microsoft 365 subscription accounts and email addresses.
Observed behavior: Adding the subscription to the Outlook account or updating contact details does not successfully transfer the subscription benefits or cloud storage capacity to the new account.

Before you start

Before proceeding, ensure you have the login credentials for both your original Gmail-based Microsoft account and your new Outlook.com account, as you will need to access both to manage your subscription renewals.

Solution 1Recommended

Turn Off Auto-Renew and Re-subscribe with the New Account

Since Microsoft does not allow the direct transfer of subscriptions between accounts, you must let the current subscription expire and start a new one on your desired Outlook.com account.

Microsoft accounts are designed in a way that prevents the direct transfer of an active Microsoft 365 subscription from one account to another. Updating your contact details will not transfer your storage capacity or Office benefits.

Log into your current account

Go to office.com/myaccount and sign in with your original Gmail-associated Microsoft account.

Access subscription settings

Navigate to the 'Services & subscriptions' section at the top of the page.

Manage your subscription

Locate your active Microsoft 365 subscription and click on 'Manage'.

Disable auto-renewal

Choose 'Turn off recurring billing' or 'Cancel subscription' to stop automatic renewal, allowing you to keep the benefits until the current billing cycle ends.

Purchase on the new account

Once the current subscription expires, log in with your new Outlook.com address and purchase a new Microsoft 365 subscription.

Important: Remember to back up any files stored on the OneDrive associated with your old Gmail account before the subscription expires, as the storage capacity will revert to the free 5GB tier.

Frequently Asked Questions

Can I merge two Microsoft accounts into one?

No, Microsoft currently does not offer a way to merge multiple Microsoft accounts or directly transfer data, active subscriptions, or digital purchases between them.

Why didn't my OneDrive storage increase when I updated my contact details to Outlook?

Cloud storage is strictly tied to the original Microsoft account that purchased the subscription. Updating contact emails or attempting to link accounts does not migrate the storage benefits to a different account.

Can I add my new Outlook.com address as an alias to my existing Microsoft account?

If the Outlook.com address is already created as a standalone Microsoft account, it cannot be added as an alias to your existing Gmail-based account. Aliases must be newly created within the account settings or use third-party email addresses.
