Fix Excel Repeatedly Requesting Sign-In for Microsoft 365

Product: Microsoft Excel
Device & OS: not provided
Scenario: Attempting to use Microsoft 365 exclusive features, such as refreshing stock market data, while the application continuously asks for authentication.
Observed behavior: Excel displays a recurring message requiring the user to sign in with an account associated with a subscription, even if the correct account is already signed in.

Solution 1Recommended

Sign Out of Unnecessary Accounts and Update Office

Resolve account conflicts by removing extra accounts and ensuring your Office applications have the latest bug fixes.

Sometimes, cached credentials or multiple accounts signed into Office can confuse the subscription validation process. Clearing these out and forcing an update can resolve the loop.

Sign out of extra accounts

Open Excel, click on 'File' in the top-left corner, and select 'Account'. Under User Information, click 'Sign out' for any account that is not associated with your primary Microsoft 365 subscription.

Restart Microsoft Excel

Close all open Excel windows completely. Reopen Excel and sign back in using only the email address tied to your active subscription.

Install Office updates

Navigate back to 'File' > 'Account'. Under Product Information, click on 'Update Options' and select 'Update Now' to ensure you have the latest patches from Microsoft.

Sign Out of Unnecessary Accounts and Update Office

Account Synchronization: Signing back in refreshes your local licensing token, often resolving false prompts about missing subscriptions.

Solution 2

Check Microsoft 365 Service Health Dashboard

Determine if the sign-in loop is caused by a known service outage on Microsoft's end.

Frequently Asked Questions

Why does Excel keep asking me to sign in even though I already am?

This usually happens due to corrupted local credential caches, multiple conflicting accounts signed in simultaneously, or a temporary Microsoft server outage affecting subscription validation.

Can I still view my Excel spreadsheets if I close the sign-in prompt?

Yes, you can typically still open and view your local files. However, you may be restricted to read-only mode, and premium connected features like Stock Data or saving to OneDrive will be disabled.

How do I refresh stock market data in Excel?

Navigate to the 'Data' tab on the ribbon and click 'Refresh All'. Note that this feature requires an active Microsoft 365 subscription and a stable connection to Microsoft's servers.
