Microsoft has introduced a new feature in its Purview compliance portal called "Recipient/Domain Count Over." This feature is like having a security guard at the entrance of a building who checks how many people are entering. If too many people try to enter at once, the guard raises an alert or takes action to ensure everything is under control.

In the context of email, this feature allows organizations to set up rules that monitor how many recipients or domains an email is being sent to. If an email is sent to more people or domains than allowed, the system can alert the appropriate team or take action to prevent the email from being sent. This is particularly useful for preventing sensitive information from being accidentally or intentionally shared with too many people, which could lead to data breaches or non-compliance with regulations.

Think of it as a digital bouncer for your email system, ensuring that only the right number of people get access to the information, much like a club that only allows a certain number of guests inside at a time. This helps organizations keep their data secure and maintain compliance with various regulatory requirements, providing an added layer of protection for sensitive information.
