Answer

That's the right way to say it: I will inform your team that you will come to the office tomorrow. I can't think of another way right now.

Answer

"That" is a conjunction that joins two related sentences. The two sentences are "I will inform your team." and "You will come to the office tomorrow." So "that" is replacing a period ".".
