The Activation of Office Pro Plus 2013 is not "sticking" in a 2008 R2 RDP Session. Office Pro Plus 2013 is installed on the RDS Host. Users authorized to access via their Office 365 Pro Plus Subscriptions.
Office Pro+ 2013 is installed and activated with appropriate MAK. Every few days or so a handful of RDS users are requested to activate the Office they are using during their sessions.
Any guidance would be phenomenal!
Thanks
