How to properly license Office on RDS server
I have a customer that is building 2 new RDS servers for their 24 users. They have Office 2013 on their existing Terminal Servers. They're on-prem Exchange, no Office 365. What I've mostly found is they'll need to purchase Office licenses per device that connects to the new RDS servers, but I've also seen a few articles that say if they have a licenses version on their workstation, that covers them...no additional licenses are needed. I can't find a document from MS that spells this out in a simple answer. Can anyone that has experience with this let me know exactly what the requirements are or link me to an article that explains it so I can share with my customer?
