Microsoft project management software used to plan, manage, and communicate a project schedule and other information among workgroup members, project managers, and other stakeholders.
Thanks Cliff,
this is the screenshot from PowerShell.
I can see that there is no Project Plan included. What I really don't understand is, why I do have access to Project Online Professional, Project for the web and to Project online desktop client. All these products are available and usable. I can create projects for all the people in my org and so on.
