- Product
- Microsoft Office 2019
- Device & OS
- Windows
- Scenario
- The user has successfully authenticated their Microsoft account, but the Office interface fails to update its status on the top ribbon.
- Observed behavior
- The Microsoft account displays correctly under Account settings, yet a 'Sign In' button persistently appears in the ribbon across all Office applications like Word and Excel.
Ensure you have your Microsoft account email and password ready, as you will need to sign out and log back in to refresh your session credentials.
Sign Out and Sign Back In to Refresh Office Authentication
This is the most effective method to force Office applications to sync their visual interface with your actual account status.
A common synchronization glitch in Office 2019 causes the ribbon to display an outdated sign-in status. Re-establishing the session usually resolves the discrepancy.
Open any Office application (such as Word or Excel), click on your profile name or the 'Sign In' button on the top right, and select 'Sign out'.
Completely close out of all running Microsoft Office applications to ensure the current authenticated session is fully terminated.
Launch an Office application again, click on 'Sign In' in the top right corner, and enter your Microsoft account credentials to restore your session.

Run Office Quick Repair via Windows Settings
Use this method if the sign-in button persists after re-authenticating, as it repairs underlying installation or registry glitches.
Switch to WPS Office to Avoid Account Sync Glitches
If Microsoft Office 2019 continues to experience persistent authentication bugs or UI glitches, consider switching to WPS Office. It provides a highly compatible, free alternative with a familiar user interface that doesn't require constant sign-in troubleshooting to function optimally.

Frequently Asked Questions
Why does my Office 2019 ribbon say 'Sign In' when I am already logged in?
This is a known visual synchronization glitch in Microsoft Office where the top ribbon interface fails to communicate properly with the backend Account settings. It is often caused by cached credentials or minor background update errors.
Will I lose my unsaved work or documents if I sign out of Office?
You will not lose locally saved documents. However, if you are actively editing files stored on OneDrive, you must save them before signing out. Signing out simply disconnects the application from your Microsoft cloud account.
What is the difference between Quick Repair and Online Repair for Office?
Quick Repair scans and fixes corrupted files locally without needing an internet connection, making it much faster. Online Repair completely uninstalls and downloads fresh Office installation files from Microsoft servers to fix deeper, more complex issues.
