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 you start

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.

Solution 1Recommended

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.

1
Contact your IT administrator

Reach out to your organization's Microsoft 365 Global Administrator or IT helpdesk to report the persistent crashing.

2
Open a support ticket

Ask the administrator to log into the Microsoft 365 Admin Center and open a formal support ticket with Microsoft Online Support.

3
Detail the symptoms

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.

4
Assist with log collection

Work with the Microsoft support engineers to collect any necessary backend logs or inspect tenant environment settings.

Escalate to Microsoft Online Support
Device Specificity: This specific crash behavior has been noted to affect iPhones exclusively. iPads running the exact same iOS 16.1.1 version and MAM policies are typically able to open SharePoint without issues.

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.
