I am and Onboarding Specialist at HubSpot with a customer who also views this as a pain point. Similiar to use cases noted above, a user does not “own” a contact until an appointment is booked. Their CRM is full of customers that are unassigned but communicate with Support regularly…if a Support Rep emails a customer and becomes their “owner”, it disrupts the sales process. I’m now trying to determine a workaround to solve for this and will report back if I find anything.
