Sure. Exchange 2010 has tightly integrated with AD RMS and provides a rich set of IRM features: Transport Protection Rules, Outlook Protection Rules, Transport Decryption, IRM in OWA, IRM Search in OWA, Journal Report Decryption, Prelicensing and Protected Voicemail. You can find detailed information on the features here: All features but Protected Voicemail and Outlook Protection Rules are supported on all versions of Outlook with AD RMS support, i.e. Outlook 2007 and up. Additionally, IRM features support Office attachments such as Word, Powerpoint etc. For example, if a Transport Protection Rule fires on a message with a Word attachment, both the message and the attachment will be RMS protected. Similarly if Journal Report Decryption attaches decrypted copies of both messages and their supported attachments into the Journal Report so that you can search both the message and attachments in your journal mailbox. Folks one IRM feature I would especially like to stress is IRM in OWA. You can now compose, read and reply to RMS protected messages natively in OWA (without an add-on) which also means you can now view RMS messages natively in browsers such as Safari and Firefox in addition to Internet Explorer.
