Email Experiment

I have been asked by an exec to look in to shutting down email for a day.  They would like for there to be email between our customers and other outside people, but no emails between people within the company.

 i.e. I can email our vendor outside our company and they can reply, but I can't email the shipping desk here.  I am thinking of doing a hub transport rule, but I am not sure what it would be.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

hub transport rule

You are correct. All you need to do is create a HT rule and block all of the internal email (drop the message) and allow anything external to go out.

You can then enable and disable the rule when you no longer want to use it.

That's it.
See screenshot below...
I wouldn't quite configure the rule as the previous poster describes.

If I understand your question correctly, the company wishes for ALL employees to be unable to email ALL other employees, but they CAN email external recipients.

In that case, I would uncheck "from people" in the previous poster's screenshot, and instead check "from users inside or outside the organization" (choose inside), so the final rule reads:

Apply rule to messages
from users inside the organization
and sent to users inside the organization
silently drop the message.

You are correct, however, in that Hub Transport rules are the simplest and most effective location to implement this.
