How do I copy/merge data from one calender into the default calend

[Guest]

I have an office group calender that I need to merge into my default calender
each day. There seems to be no way of making the default outlook calender
and my office group calender redundant?

Drag-and-drop.

You will always have an active calendar in your delivery location. A shared
calendar will never be the primary one.
