What is Microsoft Purview Information Protection?

Microsoft Purview Information Protection (MPIP) is a Microsoft rights management solution that enables a rights-based access to assets including PDF documents. Adobe Acrobat Pro/Standard and Reader desktop apps support consistent viewing of PDFs protected by Microsoft Purview Information Protection. In addition, for organizations standardizing on MPIP, we have launched the native experience to apply and edit Information Protection sensitivity labels and policies to their PDFs within the desktop version of Acrobat Pro/Standard.

For details, see Protect your sensitive data with Microsoft Purview.

Consistent Viewing of Microsoft Purview Information Protection protected PDFs in Acrobat and Adobe Reader

Users of Azure Information Protection and other Microsoft Purview Information Protection solutions can use Acrobat or Adobe Reader to read labeled and protected content. For more on Acrobat and Adobe Reader support for viewing such files, see MPIP for Acrobat and Adobe Reader.

Ensure that default and mandatory labeling settings are enabled in the Information Protection policy in Microsoft Purview Compliance Portal.

If your MPIP admin has set up default labeling for your organization, this means that if you don't set up a label, Acrobat will mark the document with the default label when you save the document. 

For modified files you will be prompted to apply the default label when saving.
