We are a hosting provider, and we are looking to spin up a Citrix XenDesktop environment within Azure for a customer. Their VDI’s will be running Office 365 ProPlus, and we are ready to get these through our indirect CSP agreement (Office 365 E3). I am told the client would need Windows 10 E3 for each user which would allow 5 installs. It is for thin clients. Is this correct?
