Device & OS: iOS (iPhone or iPad)
Scenario: Connecting Acrobat Reader Mobile to a personal OneDrive account.

Solution 1Recommended

Install and Connect the Microsoft OneDrive App

Installing the native OneDrive application allows Acrobat Reader Mobile to use the OneDrive connector directly, bypassing the Microsoft Authenticator redirection loop.

Acrobat Reader Mobile relies on the native OneDrive app integration to securely authenticate and browse files on iOS devices. If the app is missing, the system attempts to authenticate through other Microsoft apps like Authenticator, which fails to complete the connection.

Install OneDrive

Open the App Store on your iPhone or iPad, search for Microsoft OneDrive, and install the application on your device.

Access the Location Chooser

Launch Acrobat Reader Mobile on your device and tap on the 'Location Chooser' menu option.

Select More Locations

Tap on 'More Locations' from the available menu to browse the list of installed cloud storage providers.

Choose OneDrive

Select the newly installed OneDrive application from the list to grant Acrobat access to your cloud files.

Install and Connect the Microsoft OneDrive App

App Visibility Troubleshooting: If OneDrive does not appear in the 'More Locations' list, verify that the app is fully installed and updated, force close Acrobat Reader Mobile, and try the steps again.

Frequently Asked Questions

Why does Acrobat open Microsoft Authenticator on iOS?

This usually happens when the native Microsoft OneDrive application is not installed on your iPhone or iPad. Without it, Acrobat's sign-in prompt misroutes the authentication request to other Microsoft security apps.

Can I connect OneDrive to Acrobat without installing the OneDrive app?

No, Acrobat Reader Mobile requires the official OneDrive app to act as a connector to securely access your cloud files on personal iOS devices.

What if OneDrive still doesn't appear in Acrobat after I install it?

Ensure the OneDrive app is completely updated via the App Store. Once updated, force close the Acrobat Reader Mobile app, reopen it, and check the 'More Locations' menu once more.
