Karen has moved the Tuesday call to Thursday at four. Shall I confirm?

Yes.

Done. I have also moved the gym to Friday so the day reads cleanly.

The porter has the Smythson delivery. I shall have it on your desk by lunch.

Short. Considered. Rare.
SMS is for the time-sensitive judgment call: a moved meeting, a porter at the door, a question that wants a single word in reply. The thread reads like a short note slipped under the door, not a chat.
Permitted
Schedule changes. Deliveries. One-line confirmations.
Forbidden
Family matters. Long discussion. Anything wanting a paragraph.
