How to Fix OneNote on iPhone Opening an Old Organization Login Page
Product
Microsoft OneNote
Device & OS
iOS (iPhone)
Scenario
Attempting to sign in to the OneNote mobile app with a current personal or work account after leaving a previous organization.
Observed behavior
The app continuously opens the previous organization's login page, preventing normal sign-in, even after removing saved passwords and reinstalling the app.
Before you start

Before proceeding with the reset, ensure you have fully force-closed the OneNote app from your iPhone's App Switcher so the new settings can take effect properly.

Solution 1Recommended

Reset OneNote via iOS Settings

Use the built-in iOS settings menu to completely clear OneNote's cached login credentials and force the app to ask for new account details.

Simply deleting and reinstalling the OneNote app does not always remove enterprise login tokens stored securely on your iPhone. To resolve this, you must manually reset the app's data through the iOS Settings.

1
Quit the OneNote App

Swipe up from the bottom of your iPhone screen to open the App Switcher, find the OneNote preview, and swipe it up to fully close the application.

2
Open iOS Settings

Navigate to your iPhone's home screen and tap the 'Settings' app (gear icon).

3
Locate OneNote Settings

Scroll down through your list of installed applications until you find 'OneNote'. Tap on it to open its specific settings.

4
Enable Reset Options

Tap on 'Reset OneNote' under the Troubleshooting section. Toggle on the option for 'Delete Login Credentials' (and 'Delete All Notebooks' if you want a completely fresh start).

5
Restart and Sign In

Restart your iPhone. Once powered back on, open the OneNote app. You should now be prompted to enter your current Microsoft account details.

Independent App Storage: Microsoft mobile apps often store account information separately. This is why other Microsoft apps on your device may continue to function normally while OneNote requires a specific, manual reset.

Frequently Asked Questions

Why does OneNote remember my old organization's login after I uninstalled it?

iOS securely stores certain login credentials and enterprise authentication tokens in the device's keychain. Simply uninstalling an app does not always delete these secure keychain items, causing the app to retrieve the old token when reinstalled.

Will resetting OneNote delete my notebooks?

Resetting the app's login credentials will only remove the local login data and preferences. Your actual notebooks are safely stored in the cloud (OneDrive or SharePoint). Once you log in with the correct account, your notebooks will sync back to your iPhone.

What should I do if the reset option in iOS settings doesn't work?

If the problem persists, check if you have the Microsoft Authenticator app installed on your iPhone. Open it and remove the old organization's account from the list, then repeat the OneNote reset process.
