The user is unable to log into the SharePoint app on their iPad because the application repeatedly crashes and returns to the Home screen during authentication.

How to Fix SharePoint App Crashing on iPad During Sign-In

Product: Microsoft SharePoint
Device & OS: iPadOS 16.4.1
Scenario: Signing into the SharePoint mobile app on an iPad.
Observed behavior: The SharePoint application closes unexpectedly and returns to the iOS Home screen during the sign-in process, even after standard updates, restarts, and reinstallations.

Before you start

Before proceeding with advanced troubleshooting, ensure you have your Microsoft 365 credentials handy and verify if you can access your SharePoint sites via the Safari browser on your iPad as a temporary workaround.

Solution 1Recommended

Perform a Clean Reinstallation by Offloading the App

Offload the app to clear corrupted cache data that might be causing the authentication crash before reinstalling it.

A standard reinstallation sometimes leaves behind corrupted cached files. Offloading the app ensures a deeper clean of the application's core data while preserving your personal documents.

Open iPad Settings

Navigate to your iPad 'Settings', select 'General', and tap on 'iPad Storage'.

Offload the SharePoint App

Scroll down the list of installed apps to find 'SharePoint'. Tap on it and select 'Offload App' to remove the application framework while keeping its documents and data.

Reinstall SharePoint

After the offloading process finishes, tap 'Reinstall App' on the same screen, or download it again directly from the Apple App Store.

Restart and Sign In

Restart your iPad, open the newly installed SharePoint app, and attempt the sign-in process once more.

Perform a Clean Reinstallation by Offloading the App

Keep iOS Updated: Ensure your iPadOS is updated beyond 16.4.1 if a newer version is available, as Apple and Microsoft frequently patch app-breaking compatibility bugs in subsequent updates.

Solution 2

Contact Your Organization's IT Administrator

If standard local troubleshooting fails, the crash may be triggered by strict authentication policies or a known Microsoft bug requiring backend support.

Frequently Asked Questions

Why does the SharePoint app keep crashing on my iPad during sign-in?

App crashes during authentication on iPadOS can occur due to corrupted cache data, outdated app versions, compatibility bugs with a specific iOS release like iPadOS 16.4.1, or conflicts with your organization's mobile device management (MDM) policies.

Can I access my SharePoint files on an iPad without using the app?

Yes. If the dedicated SharePoint app is crashing, you can use Safari or another mobile web browser on your iPad to log into your Microsoft 365 account online and access your SharePoint sites via the web interface.

Does clearing the cache fix iPad app crashing issues?

Yes, offloading the app in your iPad Storage settings clears temporary corrupted data without deleting your stored files. This often resolves unexpected crashes that occur during authentication or immediately upon app launch.

What should I do if updating iPadOS doesn't fix the SharePoint crash?

If both standard app updates and iPadOS updates fail to fix the issue, you should report the problem to your organization's IT administrator to check for known authentication conflicts, or monitor Microsoft's official channels for an upcoming bug fix patch.
