Scroll through the app list to locate your Microsoft Office installation. Click on it (or click the three dots next to it) and select 'Modify'.

Run a Quick Repair

Choose 'Quick Repair' from the prompt window and click 'Repair'. Wait for the process to finish and check if the sign-in issue is resolved.

Frequently Asked Questions

Why does Microsoft Office keep asking me to sign in?

This usually happens when Windows encounters an issue with your Microsoft account credentials. It is often caused by corrupted security tokens, recent Microsoft account password changes, or aggressive third-party system cleaning tools deleting your saved login data.

Will running an Online Repair delete my Office documents?

No, running a Quick Repair or an Online Repair will only fix or replace the Microsoft Office application files. Your personal documents, spreadsheets, and presentations will remain safe and untouched on your computer.

Can I use Office applications without signing in?

Microsoft 365 requires you to stay signed in with an active subscription to verify your license and access cloud features. If you prefer offline editing without constant account checks, consider switching to a local-friendly suite like WPS Office.
