My customer has Office 365 ProPlus delivered from a dedicated server in my data center and know that they need to be licensed for Remote Desktop Services. What choices do they have for licensing this product?

The customer could either:

  1. get RDS SAL licenses under SPLA from the service provider, OR;
  2. Use their own volume licenses for RDS CALs, if any, provided they are covered with Software Assurance. See License Mobility through Software Assurance for more details.
