Fix Office 2019 Repeatedly Requesting Microsoft 365 Credentials
Question details
Users experience continuous prompts to enter Microsoft 365 credentials when opening Office 2019 applications like Word and Excel.
- Product
- Microsoft Office 2019
- Device & OS
- not provided
- Scenario
- Launching Office 2019 applications after they have been closed.
- Observed behavior
- Applications repeatedly request Microsoft 365 sign-in credentials despite running an Office 2019 product.
Before clearing identity caches or modifying your system registry, ensure you know your Microsoft account login email and password, as you will need them to sign back into your Office account.
Verify Product License and Run Office Repair
Check your account settings to ensure the correct Office 2019 license is active, then run the built-in update and repair tools to fix underlying software conflicts.
Open an Office 2019 application, such as Word. Click on 'File' in the top left corner, then select 'Account'. Verify your product information and license status under the Product Information section.
In the same 'Account' menu, click 'Update Options' and select 'Update Now' to force the Click-to-Run client to install any pending fixes.
If the issue persists, open the Windows Control Panel, navigate to 'Programs and Features', select your Office 2019 installation, click 'Change', and choose 'Online Repair'.
Clear the Office Identity Cache in the Registry
Clearing cached identity tokens in the Windows Registry can resolve conflicts that cause recurring Office 365 sign-in prompts on Office 2019 installations.
Avoid Sign-in Hassles with WPS Office
If Microsoft Office 2019 continues to cause login issues or conflicts with Microsoft 365, consider switching to WPS Office. It provides a lightweight, hassle-free environment without recurring subscription prompts.
Frequently Asked Questions
Why is Office 2019 asking for Microsoft 365 credentials?
This typically happens due to conflicting license caches in the system registry, especially if a trial version of Microsoft 365 was previously installed on the same device alongside Office 2019.
Will repairing Office 2019 delete my personal files?
No, running an Online Repair or Quick Repair from the Control Panel only fixes the application files and registry keys. Your personal documents and data will remain completely intact.
How do I check which version of Office I am currently using?
Open any Office application like Word or Excel, click on 'File' in the top-left corner, and select 'Account'. Your exact version and license details will be displayed under the 'Product Information' heading.
