Enterprise Mgmt " Scheduled Task's Missing"

EDIT: NielsSchefffers beat me to answering the question first, while i was writing a reply..  🙂  . Reminds me of the blog I still need to publish about those nice services that could be gone missing in action

That would be indeed the right configuration for that service. I am assuming its also started just like the WNS service :).
Normally when those services are running those IntuneMGT tasks would be there..  I am also assuming the gpo to enroll the devices in Intune is configured.

If so, what happens when recreating them?
