How to Fix OneNote Repeated Sign-Outs on iOS 18
Question details
Users are continuously signed out of their accounts on iOS 18 and forced to re-enter their full email address to access their notes.
- Product
- Microsoft OneNote
- Device & OS
- iOS 18
- Scenario
- Attempting to use the OneNote mobile app on iOS 18 without being repeatedly logged out of the active session.
- Observed behavior
- OneNote version 16.90 and earlier continuously drops the user's active session, clearing stored account data and prompting for a complete sign-in from scratch.
Ensure you have your correct Microsoft account email and password ready, as these steps will require you to log back into your account manually.
Clear Account Information and Reinstall OneNote
Resetting the app's stored account data and reinstalling the latest version resolves compatibility bugs between older OneNote versions and iOS 18.
This login loop is often caused by how iOS 18 handles legacy app data from OneNote version 16.90 and earlier. Completely clearing this data before updating usually breaks the cycle.
Open your iOS Settings, scroll down and tap on 'Apps' (or directly find the app list), then select 'OneNote'. Look for the option to reset the app or clear stored account information and enable it.
Return to your iOS home screen, long-press the OneNote app icon, tap 'Remove App', and confirm that you want to delete the app entirely from your device.
Open the App Store, search for Microsoft OneNote, and download the latest available version. Launch the app and sign in with your email address to verify the fix.
Experience Seamless Productivity with WPS Office on iOS
Tired of login glitches and compatibility issues interrupting your workflow? Switch to WPS Office, a free, lightweight, and highly stable alternative to Microsoft Office. Enjoy seamless document creation and editing on iOS 18 without unexpected sign-outs.
- 1. Download WPS Office: Search for WPS Office in the Apple App Store and download the application for free.
- 2. Sign in securely: Launch the app and create a free account or sign in via a quick third-party login method.
- 3. Edit documents flawlessly: Open your existing Office files and start working seamlessly with no unexpected session interruptions.
Frequently Asked Questions
Why does OneNote keep logging me out on iOS 18?
This is a known compatibility bug affecting OneNote version 16.90 and earlier when running on iOS 18. The operating system struggles to retain the app's legacy stored credentials, causing it to drop the session and ask for the full email address again.
Will I lose my notes if I uninstall and reinstall OneNote?
Uninstalling the app removes local temporary data, but your notes are safe as long as they were synced to your Microsoft OneDrive account before the sign-out issue occurred. They will automatically download once you sign back in.
What should I do if reinstalling doesn't stop the repeated sign-outs?
If the latest update does not resolve the issue, submit a bug report directly through the 'Help & Feedback' section in the OneNote app. You can also vote for the existing bug report on the Microsoft Feedback Portal to escalate the issue.
