Can you set up a one-on-one meeting on Outlook, but "forgot" to add the person's name to the invite?

A person seemed to have messed up by a big mistake in the company, and can be subject to being fired, but he claimed, he actually took the action and invited somebody for a one-on-one meeting on Microsoft Outlook, but he just forgot to include that person’s name / email.

We are using Outlook version 16.39. Is it actually possible to set up a one-on-one meeting (so it is a meeting with only one other person), where you would be able to send out an invite, but you can "forgot" to add the person you are inviting? I tried in my Outlook 16.39, and if I don’t type in a person’s name, Outlook would not allow me to click "Send" at all. Is it possible to set up a meeting with one person but you don’t include that person’s name / email and be able to perceive that you send out the invite?

Here is how Outlook looks like if you don’t type in any recipient:

How can a person not type in anything and be able to send it?
