Curious- Are you allowing all users to create O365 groups or limiting self-service creation?

Indeed company culture and current way of working will influence how companies will make decisions. We are a large, international company with innovation deeply embedded in our culture. We have been promoting self service a lot and are not staffed to support central administration of Groups. Not offering Groups is not an option as our employees will start using other services out their on the Internet to facilitate team collaboration.

That is why we will enable self service creation of Groups with a naming policy (grp_ in front of the group).
