How to Fix Repeated Microsoft 365 Sign-In Prompts After Creating a New Account

Product: Microsoft 365
Device & OS: not provided
Scenario: Attempting to use Microsoft 365 applications with a newly created Microsoft account instead of the original account that holds the active subscription.
Observed behavior: Office applications fail to recognize the license on the new account, resulting in repeated pop-up messages asking the user to sign in and synchronize their account.

Before you start

Ensure you have the login credentials for the original Microsoft account that was used to purchase the Microsoft 365 subscription, as purchases cannot be automatically transferred to a newly created account.

Solution 1Recommended

Sign in with the Original Purchase Account

Use the Microsoft account tied to your active Microsoft 365 subscription to successfully authenticate and stop the repeated prompts.

Creating a new Microsoft account does not transfer your existing Microsoft 365 license. Office applications will continue to ask for authentication until they are linked to the account that actually owns the subscription.

Verify your active subscription

Open a web browser and navigate to office.com/myaccount. Sign in with your original Microsoft account to confirm your Microsoft 365 subscription is active.

Sign out of the new account in Office

Open any Office application like Word or Excel. Go to 'File' > 'Account' (or 'Office Account'). Click 'Sign out' to remove the newly created account.

Sign in with the original account

Click 'Sign In' on the Account page and enter the email address and password of the original Microsoft account that holds the subscription.

Changing Email Addresses: If you want to use a new email address, do not create a new Microsoft account. Instead, add the new email as an 'alias' to your existing Microsoft account through the account settings.

Solution 2

Clear Old Cached Credentials

Remove stored Microsoft account passwords from your device to prevent Windows from automatically attempting to log in with the wrong account.

Frequently Asked Questions

Can I transfer my Microsoft 365 subscription to a new Microsoft account?

No, Microsoft does not allow the direct transfer of an active Microsoft 365 subscription from one account to another. You must continue using the original purchasing account or wait for the subscription to expire and repurchase it on the new account.

Why does Office keep asking me to sign in after I changed my email?

If you created an entirely new Microsoft account with your new email, Office doesn't recognize it as holding a valid license. It will continuously prompt for sign-in until you authenticate with the account that actually owns the subscription.

How do I correctly change the email address for my Office subscription?

To change your email, log into your existing Microsoft account at account.microsoft.com, navigate to your profile information, and add your new email as an 'alias'. You can then set this alias as your primary email without losing your subscription.

What should I do if my original Microsoft account was compromised?

Do not simply abandon the account and create a new one, as you will lose your purchases. Instead, contact Microsoft Support immediately to recover and secure your original account.
