RPMSG file extension - Microsoft Restricted Permission Message

What is rpmsg file? How to open rpmsg files?

File extension rpmsg is used for files that contain Microsoft Restricted Permission messages that are protected by free Information Rights Management service developed by Microsoft and supported by Microsoft Outlook version 2003 and higher and it is also supported by Outlook for Mac.

The rpmsg message file is protected by encryption and can be viewed in Outlook used by recipient.

Microsoft also recommends Rights Management Add-on for Internet Explorer that allows users to view Information Rights Management protected data (seems to be obsolete).

A restricted-permission message can only be viewed by the intended recipient and is subject to restrictions on printing, editing, or copying much like a rights-managed HTML file.
