Using Adobe Acrobat Reader with the Adobe plug-in

A collaboration between Microsoft and Adobe gives you a more simplified and consistent experience for PDF documents that have been classified and optionally, protected. This collaboration provides support for Adobe Acrobat native integration with Microsoft Information Protection solutions, such as Azure Information Protection.

This native integration has the following benefits:

  • You can view PDF documents that have been protected because they contain sensitive information.

  • You can see the classification value for your organization's label that has been applied to the document.

  • Support for the ISO standard for PDF encryption.

    Unless this capability has been disabled by an administrator, this protected PDF file format is enabled by default for the Azure Information Protection client (classic) and is always used by the Azure Information Protection unified labeling client.

You can use the Adobe plug with Windows and MacOS.
