How to Fix Cannot Sign In to OneNote on Android Phone

Product: Microsoft OneNote
Device & OS: Android
Scenario: Attempting to sign in to a Microsoft school account within the OneNote Android application.
Observed behavior: The application displays a "Can’t sign in. Please try again later" error message and blocks access to the account.

Before you start

Verify that your Android device has a stable internet connection and manually copy any unsynced offline notes to another app to prevent permanent data loss during troubleshooting.

Solution 1Recommended

Clear OneNote App Cache and Data

Clearing the app's cached files and temporary data can often resolve corrupted authentication files blocking the sign-in process.

Over time, the OneNote app collects temporary data that may become corrupted, especially after system updates or network changes. Clearing this data forces the app to initiate a fresh connection with Microsoft's servers.

Open Android Settings

Navigate to your Android device's Settings menu and select 'Apps' or 'App Management'.

Locate OneNote

Scroll through your list of installed applications and tap on 'OneNote'.

Clear Cache and Data

Tap on 'Storage & cache', then press 'Clear Cache' followed by 'Clear Data' (or 'Clear Storage'). Restart the app and attempt to sign in again.

Data Deletion Warning: Clearing app data will remove your local account configuration and any notes that have not yet synced to the cloud.

Solution 2

Check App Updates and Permissions

Outdated software or missing device permissions can prevent the app from completing the multifactor authentication process.

Solution 3

Contact Your School's IT Administrator

If local troubleshooting fails, your device may be blocked by institutional security policies.

Frequently Asked Questions

Why does my school account work on my computer but not on my Android phone?

Your school's IT department may have configured conditional access policies that allow logins from recognized campus networks or registered computers, but actively block unauthorized or unmanaged personal mobile devices.

Will reinstalling the OneNote Android app delete my local notes?

Yes, uninstalling the app or clearing its data will permanently delete any offline notes that have not yet synced to your Microsoft account. Always back up unsynced information manually before reinstalling.

Can an active VPN connection cause login errors with Microsoft apps?

Yes, using a Virtual Private Network (VPN) can route your traffic through an unexpected IP address, which may trigger Microsoft's automated security flags and block the login attempt for school accounts. Try disabling the VPN and signing in again.

What should I do if my Multifactor Authentication (MFA) fails during login?

Ensure your Android phone's date and time are set to 'Automatic', as time discrepancies can invalidate MFA codes. If the authenticator app still fails, try selecting 'Sign in another way' to receive the code via SMS or email.
