You can often view a protected file by simply opening it. For example, you might double-click an attachment in an email message, a document in File Explorer, or a link to a file and be able to open the protected file.

If you are trying to open a protected file that has a .pfile name extension, like a .ppng, then you will need to use the Microsoft Purview Information Protection viewer or the Azure Information Protection mobile viewer (AIP mobile viewer). These viewers can open protected text files, protected image files, protected PDF files, and all files that have a .pfile file name extension on Windows, Android, or iOS.

If you are trying to open a protected PDF, then you also have the option of using a supported PDF reader, such as Microsoft Edge, to open it. For more information, see View protected PDFs using Microsoft Edge on Windows or Mac.

  7.  If you want to print the file, click Print.

  8. If you want to edit the file, click Save As. This creates a copy of the file without protection.

Prompts for authentication

Before you can view the protected file, the Rights Management service that was used to protect the file must first confirm that you are authorized to view the file. The service performs this confirmation by checking your user name and password. In some cases, these credentials might be cached and you do not see a prompt that asks you to sign in. In other cases, you are prompted to supply your credentials.

If you organization does not have a cloud-based account for your to use (for Microsoft 365 or Microsoft Azure) and does not use an equivalent on-premises version (Azure Directory Rights Management Services), you have two options:

  • If you were sent a protected email, follow the instructions to sign in with your social identity provider (such as Google, if you are using a Gmail account) or apply for a one-time passcode.

  • You can apply for a free account that will accept your credentials so that you can open documents that are protected by Rights Management. To apply for this account, click the link to apply for RMS for individuals and user your company email address rather than a personal email address.
