Block emails which go outside organisation

Hello all
Can you please kindly advise if there is any rule which I can set up to avoid users from sending emails outside the company.

The email should first go to an independent authorizer and depending whether it is rejected or accepted then the email should go out from the organization.

I need this logic in office 365.
If such a functionality is not available then can any code be run which can be used alongside outlook to get this feature.

@sreejukg.. Thank you very much for your reply. As I am not much of a tech person. I want to understand if the rules will allow me to do the below steps.

Example

  1. Email sent externally by employee

  2. Notification goes to manager who looks at the email and then either rejects or approves

  3. If approved then email will go out automatically

  4. If rejected then back to user stating it has been rejected

What functionality in office 365 does one have to switch on to get these rules. Not everyone is an admin who will have access to the admin tool to change rules

Based on your scenario, you may use Moderated Recepients feature along with Mail flow.

Hope this helps

You could take the steps below to create transport rule:

  1. Login Exchange online admin center.

  2. Create a new Transport rule from "Mail Flow→Rules"

  3. Click more options:
