I'm trying to install Dynamics Marketing from the setup wizard on a sandbox instance. We already have a portal attached. When I check the box to have the event website run on the portal I get this error message:
No portals are available for your selected Dynamics 365 organization.
Is the setup looking for an unused portal license because Marketing has to have a separate portal of its own? I can't move past this unless I say we'll host it externally but I don't want the end users to have to manually updating a website every time an event is added when the portal option would do this automatically.
