  • Hi,

    As far as I know, IRM is a subset of RMS.

    From the "Information Rights Management in the 2007 Microsoft Office system", we can find:

    "To use IRM in the 2007 Office release, the minimum required software is Windows Rights Management Services (RMS) Client Service Pack 1 (SP1)."

    "The RMS administrator can configure company-specific IRM policies that define who can access information and what level of editing is permitted for an e-mail message."

    So, IRM also leverage the RMS client software.

    Thanks.

  • Hi,

    Generally speaking, AD RMS could cooperate with more products and protect files while IRM mainly protects Office documents. The following article explains limitation of IRM clearly.

    Regarding protecting SharePoint, it’s suggested to read the following article.

  • But Mostly they are used with each other. For Example IRM is used to secure the documents while the users (or the author ) are contained in AD . So IRM needs their credentials from AD and keeps RMS data at server.

    Can we say RMS is server side implementation for protecting Information while IRM is client of AD RMS.
