You already know that the standard solution for sharing a calendar is to use a mailbox. I think you're looking for the answer to a different question: The standard solution for sharing activity information across multiple users is to employ a CRM application.

That makes sense. And i believe the same answer applies to the
following.
I was asked to pose this question/thought.
To keep matters simple, let me identify that there is a Master
Calendar - the default one built in - and then there is the user we
created called "LEB Master Calendar". Because the default Master
Calendar cannot handle their use of it, we created LEB Master Calendar
as a user, and now everyone opens the user LEB Master Calendar's
Calendar and uses it as a group "Master Calendar".
Given that clarification, everyone already opens the LEB "Master
Calendar as a secondary mailbox in their Outlook profile". So the only
thing we would need then is to know how to create "...a new Activities
group on each contact's folder that points to the Master Calendar
calendar folder" to see if there were some feasible way to do this
easily on a case-by-case basis or to somehow do it for all Contacts.

Each contacts folder would need an activities group added manually in the Properties dialog for that folder.
