Update the PDF Viewer and Related Applications

Software providers frequently release updates to enhance enterprise DRM compatibility. Updating your app is the primary step to resolving functionality limitations.

Microsoft Information Protection (MIP) requires up-to-date decryption and authentication modules within the app. Using an outdated version of your PDF viewer on iOS can prevent the app from properly verifying your editing permissions.

Check for updates

Scroll down to see pending updates and release notes. Locate your specific PDF viewer application.

Frequently Asked Questions

What is a MIP-protected PDF?

A MIP-protected PDF is a document secured by Microsoft Information Protection. It uses encryption and enterprise rights management to restrict specific actions, such as viewing, editing, copying, or printing, based on the user's authenticated permissions.

Why are editing features restricted on my mobile PDF viewer?

Many mobile PDF viewers have limited functionality when handling complex enterprise Digital Rights Management (DRM) protocols like MIP. The software may only support read-only access on mobile devices, or the app version might lack the latest decryption modules.

Can I bypass MIP protection to edit the document?

No, MIP protection cannot be bypassed. You must authenticate with an authorized enterprise account that has been granted editing permissions by the document owner. If you have the correct permissions but still cannot edit, the issue is likely a software limitation on the mobile platform.

How do I remove MIP protection from a PDF?

Only the original author or an authorized administrator can remove MIP protection. They must open the document in the authoring software (like Microsoft Word or Adobe Acrobat on a desktop) using their credentials, change the sensitivity label or permissions, and save an unprotected copy.
