Question details

The user is trapped in an authentication loop where Microsoft Word continuously requests a Microsoft 365 sign-in but fails to actually log in or authenticate the active subscription.

Product: Microsoft Word
Device & OS: not provided
Scenario: Attempting to use Microsoft Word for document editing with an existing Microsoft 365 account.
Observed behavior: Word repeatedly opens sign-in prompts without completing the login process, restricting access to features and displaying activation errors despite a previously working subscription.

Before you start

Ensure you have a stable internet connection and verify that your Microsoft 365 subscription is currently active via the Microsoft account portal.

Solution 1Recommended

Verify Account Information and Activation Status

Checking the built-in Account settings in Word helps identify if the software is failing to recognize your subscription or if a specific activation error code is being triggered.

Authentication loops often occur when the Office client is out of sync with your Microsoft 365 account status. By inspecting the Account page, you can determine if the wrong account is logged in or if the product requires reactivation.

Launch Microsoft Word

Open the Microsoft Word application on your computer. If the sign-in prompt appears immediately, close or bypass it if possible to access the main interface.

Navigate to Account Settings

Click on 'File' in the top-left corner of the ribbon menu, then select 'Account' from the bottom of the left-hand navigation pane.

Review Product Information

Look at the right side of the screen under 'Product Information'. Note whether Word displays an 'Activation Required' message or any specific error codes.

Check User Information

On the left side under 'User Information', verify that the connected email address matches the account associated with your active Microsoft 365 subscription. If it is incorrect, click 'Sign out' and attempt to log in with the correct credentials.

Check for Multiple Accounts: If you have multiple Microsoft accounts (e.g., a personal account and a work/school account) connected to Windows, they may conflict. Ensure only the account with the active subscription is used.

Frequently Asked Questions

Why does Word keep asking me to sign in?

This usually happens due to corrupted cached credentials on your device, an expired Microsoft 365 subscription, or multiple Microsoft accounts conflicting within the Office apps.

How do I clear cached credentials for Microsoft Word on Windows?

You can clear cached credentials by opening the Windows Control Panel, going to 'Credential Manager', selecting 'Windows Credentials', and removing any entries that start with 'MicrosoftOffice'.

Will reinstalling Word fix the sign-in loop?

Reinstalling can help if the installation files are deeply corrupted. However, running the Microsoft Support and Recovery Assistant (SaRA) tool or clearing your account credentials is often much faster and more effective.
