Adobe Acrobat recently updated their application to include deeper integration with Microsoft including access to OneDrive for Business files. This integration allows users to access their OneDrive for Business files from the Acrobat app. The improvements have a few configuration changes which will require that Intune admins approve the Adobe Acrobat app to connect to the Intune service. This is a one-time approval that you may not have had to do historically when connecting Adobe Acrobat and OneDrive for Business.
There are two options for this one-time approval:
Use the latest Adobe Acrobat iOS and Android app and enable the OneDrive feature:
Adobe Acrobat Reader for PDF approval prompt
