Question details

Users need a solution to stop Microsoft 365 Office applications on Android from continuously prompting for sign-in.

Fix Office Apps on Android Repeatedly Requesting Microsoft 365 Sign-In

Product: Microsoft 365 (Word, Excel, OneNote)
Device & OS: Android
Scenario: Using Microsoft Office apps on an Android device with an active Microsoft 365 subscription.
Observed behavior: The apps repeatedly display sign-in warnings and request authentication to sync, even though the user is already signed in. Tapping the warning temporarily clears it, but the issue returns.

Before you start

Before troubleshooting, ensure your Android device has a stable internet connection and verify that your Microsoft 365 subscription is active by logging into your account via a web browser.

Solution 1Recommended

Remove and Re-add the Microsoft Account

Resetting the account connection from the Android system settings can resolve persistent authentication glitches causing the sign-in loop.

Authentication tokens can sometimes become corrupted or fail to sync correctly between the Android system and Microsoft servers. Removing the account completely and adding it back forces the system to generate a fresh, valid authentication token.

Access Android Settings

Open the Settings app on your Android device and navigate to the 'Accounts' or 'Passwords & Accounts' section.

Remove the Microsoft Account

Locate your Microsoft or Work/School account in the list, tap on it, and select 'Remove Account'. Confirm the action when prompted.

Sign Back In

Open an Office app like Word or Excel. Tap the sign-in prompt and enter your Microsoft 365 credentials to re-authenticate.

Account Sync Restored: After re-adding the account, wait a few moments for your files and notebooks to sync completely.

Solution 2

Update Android OS and Microsoft 365 Apps

Outdated system software or app versions can cause compatibility issues leading to repeated login requests.

Solution 3

Contact Microsoft Support with Diagnostics

If the issue persists across multiple devices and updates, it may require advanced diagnostics from Microsoft Support.

Frequently Asked Questions

Why do my Office apps on Android keep asking me to sign in?

This can happen due to a glitch in the authentication cache, an outdated app version, or sync issues between the Android system and Microsoft 365 servers.

Will clearing app data or removing my account delete my Microsoft 365 documents?

Clearing app data or removing the account from Android settings will only remove local app settings and temporary files. It will not delete documents saved safely in your OneDrive or SharePoint.

Does this sign-in loop issue affect Microsoft 365 on Windows?

Usually, no. Many users report that while their Android apps repeatedly request sign-in, their Windows desktop apps continue to function normally without authentication issues.
