Fix Adobe Acrobat iOS OneDrive Sign-In Blocked by Intune MAM
Question details
Users are unable to sign into OneDrive using Adobe Acrobat on iOS because the app defaults to an unmanaged Safari-based web view, which violates Intune MAM Conditional Access policies.
- Product
- Adobe Acrobat Reader for iOS
- Device & OS
- iOS
- Scenario
- Attempting to sign into OneDrive from Adobe Acrobat Reader on an iOS device protected by Microsoft Intune MAM and Conditional Access.
- Observed behavior
- OneDrive authentication is blocked because Acrobat utilizes the iOS system web view (Safari) instead of Microsoft Edge, causing it to fail Conditional Access managed-browser requirements.
Verify that Microsoft Edge is installed on your iOS device and consult with your IT administrator to confirm your organization's Conditional Access policies regarding managed browsers.
Review Intune App Protection and Managed Browser Settings
Ensure Microsoft Edge is properly configured as the required managed browser in your organization's MAM policies and check for potential Intune configuration adjustments.
Because Adobe Acrobat Reader relies on the native iOS system web view for authentication, it bypasses managed browser applications like Microsoft Edge. Resolving this primarily requires IT administrative adjustments in Microsoft Endpoint Manager.
Ensure that the Microsoft Edge application is installed on the affected iOS device and properly enrolled in your organizational account.
Contact your IT administrator to verify that Microsoft Edge is correctly configured and deployed under the Intune Mobile Application Management (MAM) policies.
Have your IT admin review the Conditional Access policy settings in the Microsoft Endpoint Manager admin center to determine if specific exclusions or app-based exceptions can be created to accommodate Acrobat's system web view.
Contact Microsoft and Adobe Support for Enterprise Workarounds
Escalate the issue to the respective support teams since this is an app-level limitation involving third-party integrations.

Frequently Asked Questions
Why does Adobe Acrobat on iOS use Safari instead of Edge for sign-in?
Acrobat Reader on iOS relies on the Apple system's built-in web view framework for user authentication. By default, iOS uses a Safari-based web view, which bypasses managed enterprise browser settings like Microsoft Edge.
Can I manually set Microsoft Edge as the authentication browser in Acrobat iOS?
No, Adobe Acrobat Reader for iOS currently does not offer an in-app setting to change the default browser used for cloud authentication.
How does Intune Conditional Access block the OneDrive sign-in?
Intune policies often require users to authenticate via a recognized managed browser (like Edge) to ensure data security. Because Acrobat forces the use of an unmanaged Safari web view, the Conditional Access policy automatically blocks the connection.
Will setting Edge as the default iOS browser fix this issue?
Unfortunately, no. Changing the default browser in your iOS system settings will not affect how Adobe Acrobat handles its internal authentication, as it still calls upon the core iOS web view.
