PDF readers that support Microsoft Information Protection
If you need to open a PDF document that's been protected by Microsoft Information Protection, use the following links and information.
A PDF document that has been protected is likely to contain sensitive information. For added security, the document is encrypted so that unauthorized people can't read it, and that authorized people cannot share screens or screenshots displaying the document.
To open this document, you need a reader (sometimes called a viewer) that verifies you have been granted permissions to open the document, and then decrypt it for you.
Install PDF readers for your device

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.
For more information, see the following blog posts:
Use the links from this page to install a PDF reader so that you can open protected PDF documents.
If you need help using the reader after it's installed, use the instructions and documentation that accompanies that reader. For example, for the Azure Information Protection viewer for Windows, see User Guide: View protected files with the Azure Information Protection unified labeling client.
