How to Fix Microsoft 365, OneDrive, and OneNote Sign-In Errors on Android
Question details
The user is unable to sign in to Microsoft 365 mobile applications, including OneDrive, OneNote, and Outlook, on an Android device despite successful browser access.
- Product
- Microsoft 365
- Device & OS
- Android
- Scenario
- Attempting to log into Microsoft 365 mobile apps on a secondary Android device or monitor setup.
- Observed behavior
- The apps fail to authenticate, getting stuck on 'App getting ready', displaying 'Wait a moment while we sign you in from another app', or throwing permission errors, even after reinstalling the apps.
Verify that your internet connection is stable and try signing into your Microsoft 365 account via a mobile web browser to confirm your account is active and not locked by your organization.
Clear App Data and Remove Account from Device
Clearing corrupted authentication tokens and cache from your Android device can often resolve sign-in loops and permission errors.
Authentication loops often occur when corrupted login tokens are shared among multiple Microsoft applications on the same device. Completely removing the account from Android settings before signing in again can clear these broken tokens.
Go to your Android 'Settings', select 'Apps' or 'App Management', and find 'OneDrive' (or the affected app). Tap 'Storage & cache', then select 'Clear Storage/Data'.
Return to the main Android 'Settings' menu, scroll down to 'Accounts' or 'Passwords & accounts'. Locate your Microsoft or Office account, tap it, and select 'Remove account'.
Restart your Android device. Open the affected Microsoft 365 application and attempt to sign in again from scratch.
Escalate to Your Microsoft 365 IT Administrator
If troubleshooting fails and browser access works, the issue likely stems from organizational device management or backend authentication rules that require an IT support ticket.

Frequently Asked Questions
Why is my Microsoft 365 Android app stuck on 'App getting ready'?
This loop usually occurs when the app's sign-in token becomes corrupted or conflicts with another Microsoft app on your device. Clearing the app's cache and data from Android settings is usually required to fix it.
Does reinstalling the Microsoft app fix sign-in loops?
Not always. Reinstalling an app sometimes leaves background account data or corrupted tokens intact within the Android system. You must manually remove the Microsoft account from Android's 'Accounts' settings to completely reset the sign-in process.
How do I test if the issue is with my account or the app?
Open a mobile web browser (like Chrome) on your Android device and navigate to the Microsoft 365 login page. If you sign in successfully, your account is fine, and the issue is isolated to the mobile application or device configuration.
Can device management apps block Microsoft 365 sign-ins?
Yes. If your organization uses Mobile Device Management (MDM) platforms like Microsoft Intune, non-compliant devices, missing security certificates, or conditional access policies can silently block mobile apps from authenticating.
