How to Fix Microsoft 365 Mobile Links Prompting for Sign-In
Question details
Users sharing Word documents via 'Anyone' links find that mobile recipients are incorrectly prompted to sign in when attempting to open the link.
- Product
- Microsoft 365 Mobile App
- Device & OS
- Android and iOS
- Scenario
- Opening a shared Word document via an 'Anyone' link on a mobile device where the Microsoft 365 app is installed.
- Observed behavior
- The link automatically redirects to the Microsoft 365 app and demands a sign-in, instead of opening the document directly for anonymous viewing in the browser.
Verify that the shared link was actually generated with 'Anyone with the link can view' permissions by testing it in an incognito window on a desktop computer before troubleshooting the mobile device.
Uninstall or Disable the Microsoft 365 Mobile App
Since the Microsoft 365 app automatically intercepts links, removing it temporarily forces the link to open in the mobile browser, respecting the anonymous access permissions.
This is the most reliable workaround because there is currently no standard SharePoint setting to prevent the mobile app from taking over document URLs.
Go to your device's home screen or settings, locate the Microsoft 365 app, and select 'Uninstall' or 'Remove App'.
Tap the shared 'Anyone' link again. It will now open in your default mobile web browser (like Safari or Chrome).
The document should now display natively in the browser without prompting you to sign in with a work or school account.
Force the Link to Open in a New Browser Tab
Bypass the automatic app redirection by forcing your mobile device to open the shared link directly in the web browser.
Sign In with a Free Personal Microsoft Account
Satisfy the app's sign-in prompt by using a free personal Microsoft account to bypass the block.
Try WPS Office for Hassle-Free Mobile Document Viewing

- 3. Open Documents Seamlessly: Use WPS Office to open your downloaded Word documents locally without being forced into a sign-in loop.
Frequently Asked Questions
Why do 'Anyone' links prompt for sign-in on mobile devices?
When the Microsoft 365 app is installed on an iOS or Android device, the operating system routes SharePoint and OneDrive links directly to the app. If no eligible work or school account is signed in, the app blocks access and demands authentication, overriding the 'Anyone' link settings.
Can I change a Microsoft 365 setting to stop this redirection?
Currently, there is no standard SharePoint or Microsoft 365 admin setting to prevent the mobile app from automatically intercepting these shared links. The behavior is controlled by how the mobile operating system handles universal links.
Does this sign-in issue affect desktop users?
No. Desktop users opening 'Anyone' links in private or incognito browser windows can typically access the document without being prompted to sign in, as the browser handles the anonymous session natively.
