How to Fix SharePoint App Repeatedly Signing Out on iPhone
Question details
The user is experiencing persistent sign-out issues with the SharePoint iOS app on their iPhone.
- Product
- Microsoft SharePoint iOS App
- Device & OS
- iPhone (iOS)
- Scenario
- Attempting to stay securely logged into the SharePoint mobile application to access organization files.
- Observed behavior
- The app repeatedly signs the user out automatically, despite reinstalling the app, clearing its cache, updating iOS, and changing networks. The same account functions normally on an iPad.
Ensure you have your Microsoft 365 account credentials handy and verify your internet connection before proceeding with the account reset.
Clear SharePoint Account Settings via iOS Settings
Resetting the specific account settings for SharePoint directly through the iOS Settings app resolves persistent cached authentication errors.
Often, simply reinstalling the app does not clear deep-seated authentication tokens on iOS. Using the built-in system toggle forces a clean slate for the app's login cache.
Navigate to your iPhone's home screen and tap the 'Settings' app icon.
Scroll down through the list of installed applications and tap on 'SharePoint'.
Tap on 'Reset' within the SharePoint settings menu.
Toggle the switch next to 'Clear Account Settings' to the 'On' (green) position.
Launch the SharePoint app again. You will be prompted to sign in freshly with your Microsoft 365 credentials.
Escalate to Microsoft 365 Administrator
If local troubleshooting fails, the issue might be related to device-specific conditional access policies configured by your organization.
Experience Stable Document Management with WPS Office
While dealing with persistent login issues in specialized apps can be frustrating, WPS Office offers a highly stable, lightweight, and free alternative for viewing, editing, and managing your Office documents across all your iOS devices.
- 1. Download the App: Search for WPS Office in the Apple App Store and download the free application to your iPhone.
- 2. Connect Your Cloud: Open the app, go to the 'Cloud' tab, and link your preferred cloud storage service to access your documents.
- 3. View and Edit Documents: Tap on any Word, Excel, or PowerPoint file to start viewing and editing directly from your mobile device securely.
Frequently Asked Questions
Why does my SharePoint app keep signing out only on my iPhone?
This usually happens due to corrupted authentication tokens or cached data specific to the iOS installation environment. It can also be caused by specific device compliance policies set by your IT department that flag your iPhone.
Will reinstalling the SharePoint iOS app fix the sign-in issue?
Reinstalling the app alone often doesn't remove hidden cached credentials stored in the iOS keychain. You must explicitly use the 'Clear Account Settings' toggle in the iOS Settings to force a completely fresh authentication state.
What if clearing the SharePoint account settings doesn't work?
If the problem persists after clearing the account settings, it is likely caused by an organizational policy issue. You should contact your IT administrator to review your Microsoft 365 conditional access and sign-in logs for specific error codes.
