Retirement notification for the Azure Information Protection mobile viewer and RMS Sharing App

Over a decade ago, we launched Azure Information Protection (AIP) mobile app for iOS and Android and Rights Management Service (RMS) Sharing app for Mac to fill an important niche in our non-Office file ecosystem to enable users to securely view protected filetypes like (P)PDF, RPMSG and PFILEs outside of Windows. These viewing applications are integrated with sensitivity labels from Microsoft Purview and encryption from the Rights Management Service to view protected non-Office files and enforce protection rights. Today, usage of these app is very low, especially for file types other than PDFs. Most PDF use cases have already shifted to native Office apps and modern Microsoft 365 experiences. As part of our ongoing modernization efforts, we’ve decided to retire these legacy apps.

In this blog post, we will cover what you need to know about the retirement, share key resources to support your transition, and explain how to get help if you have questions.

Q. How do I view protected non-Office files on iOS and Android?

Instead of one application for all non-Office file types, view these files in apps where you’d most commonly see them. For example, use the OneDrive app or the Microsoft 365 Copilot app to open protected PDFs. Here’s a summary of which applications support each file type:

1) PDF and PPDF: Open protected PDF files with Microsoft 365 Copilot, OneDrive or Edge. These applications have native support to view labels and enforce protection rights. Legacy PPDF files must be opened with the Microsoft Information Protection File Labeler on Windows and saved as PDF before they can be viewed.

2) PFILE: These files are no longer viewable on iOS and Android. PFILEs are file types supported for classification and protection and include file extensions like PTXT, PPNG, PJPG and PXML. To view these files, use the Microsoft Purview Information Protection Viewer on Windows.

3) RPMSG: These files are also no longer viewable on iOS and Android. To view these files, use Classic Outlook on Windows.

Q. Where can I download the required apps for iOS, Android or Windows?

These apps are available for download on the Apple App Store, Google Play Store, Microsoft Download Center or Microsoft Store.

• Microsoft 365 Copilot: Android / iOS
• Microsoft OneDrive: Android / iOS
• Microsoft Edge: AI browser: Android / iOS
• Microsoft Purview Information Protection Client: Windows
• Classic Outlook for Windows: Windows

Q. Is there an alternative app to view non-Office files on Mac?

Before May 30, 2026, we will release the Microsoft Purview Information Protection (MPIP) File Labeler and Viewer for Mac devices. This will make the protected non-Office file experience on Mac a lot better with the ability to not only view but modify labels too. Meanwhile, continue using the RMS Sharing App.

Q. Is the Microsoft Purview Information Protection Client Viewer going away too?

No. The Microsoft Purview Information Protection Client, previously known as the Azure Information Protection Client, continues to be supported on Windows and is not being retired. We are actively improving this client and plan to bring its viewing and labeling capabilities to Mac as well.

Q. What happens if I already have RMS Sharing App or AIP Mobile on my device?

You can continue using these apps to view protected files and download onto new devices until retirement on May 30, 2026. At that time, these apps will be removed from app stores and will no longer be supported. While existing versions may continue to function, they will not receive any further updates or security patches.

Q. I need more help. Who can I reach out to?
