Relevant for: AIP unified labeling client and classic client
Note
To provide a unified and streamlined customer experience, the Azure Information Protection classic client and Label Management in the Azure Portal are deprecated as of March 31, 2021. While the classic client continues to work as configured, no further support is provided, and maintenance versions will no longer be released for the classic client.
We recommend that you migrate to unified labeling and upgrade to the unified labeling client. Learn more in our recent deprecation blog.
This article describes the protected PDF readers that are supported for Azure Information Protection (AIP). Protected PDF readers enable users to open those encrypted PDFs and view the sensitive information contained.
Encrypting your PDFs with AIP ensures that unauthorized people cannot read the file's content. Protected PDF readers that support AIP verify that you've been granted permissions to open the document, and also decrypt the content for you.
For example, the following image shows an encrypted document open in Adobe Acrobat Reader. The bar at the top indicates that the document is protected by a Microsoft Information Protection solution.
For instructions, see the following sections:
Tip
If your document doesn't open after installing a recommended reader, the document may be protected in an older format.
In this case, try one of the readers listed as supported for previous formats. For more information, see Support for previous formats.
ISO standards for PDF encryption
The PDF readers referenced on this page can all open protected documents that adhere to the ISO standard for PDF encryption.
This standard is used by default by the AIP client.
Note
Classic client only: If you have the AIP classic client, this may have been disabled by an administrator.
