Hi,

Please see this FAQ:

Q: How can an Office 365 customer purchase Microsoft Rights Management Services (RMS)?

A: RMS is already included in the Office 365 Enterprise E3, and E4 plans and the Education A3 and A4 plans. RMS is also available as an add-on in the E1 and A2 plans. Consumption of rights-protected content is free. A license is required to protect content.
