Fix SharePoint iPhone App Crashing on iOS 16.1.1
Question details
The SharePoint mobile app crashes immediately upon opening on iPhones running iOS 16.1.1.

- Product
- Microsoft SharePoint
- Device & OS
- iOS 16.1.1
- Scenario
- Launching the SharePoint app on an iPhone to access company documents and sites.
- Observed behavior
- The app displays a brief blank white screen and then closes automatically. Reinstalling or modifying app protection policies fails to fix it, while iPads on the same OS work correctly.
Before proceeding, check if there is a newer iOS update available for your iPhone, and verify whether other Microsoft 365 mobile applications are experiencing similar startup crashes.
Escalate to Microsoft Online Support
Because standard troubleshooting methods fail, this issue requires backend investigation and log collection by Microsoft support engineers.
In cases where the SharePoint iPhone app crashes before Mobile Application Management (MAM) can even log an event, end-user troubleshooting is often insufficient. The issue is likely related to specific tenant policies affecting the iPhone build of the application.
Reach out to your organization's Microsoft 365 Global Administrator or IT helpdesk to report the persistent crashing.
Ask the administrator to log into the Microsoft 365 Admin Center and open a formal support ticket with Microsoft Online Support.
Ensure the ticket clearly states that the crash occurs specifically on iOS 16.1.1 iPhones, shows a brief white screen, and closes before app protection logging begins.
Work with the Microsoft support engineers to collect any necessary backend logs or inspect tenant environment settings.

Verify Installation and Policy Settings
Ensure you have exhausted all basic troubleshooting and policy testing before escalating the ticket.
Try WPS Office for Your Mobile Document Needs
If persistent Microsoft 365 app crashes on your iPhone are preventing you from working, consider switching to WPS Office. It provides a lightweight, highly stable mobile app for viewing, editing, and managing your essential documents without the hassle of complex tenant policies.
- 1. Download from the App Store: Search for WPS Office in the Apple App Store and download the free application to your iPhone.
- 2. Sign in or create an account: Open the app and easily sign in using your email or third-party accounts to sync your files.
- 3. Access your files: Link your preferred cloud storage or open local files directly to seamlessly continue your work.

Frequently Asked Questions
Why does my SharePoint app show a white screen and close on my iPhone?
This is a known issue on iOS 16.1.1 where the app closes before Mobile Application Management (MAM) protection policies can successfully process and log the launch event. It generally requires Microsoft's backend support to resolve.
Will reinstalling the SharePoint app fix the iOS 16.1.1 crash?
In most reported cases for this specific issue, reinstalling the app—even when switching from an MDM installation to the Apple App Store—does not resolve the brief white screen crash.
Why does SharePoint work on my iPad but not my iPhone with the same iOS version?
The iPhone and iPad versions of the app handle tenant policies and MAM protection slightly differently. The iPhone build crashes before reaching the point where the iPad successfully processes and applies the security policy.
