Restrict Email Address

To avoid sending emails to any internal or external e-mail address other than [e-mail], you can apply the following configuration steps in order.

Login to https://ExchangeServer/ecp with Organization Admin authority. Go to Mail Flow> Rules and add a new rule from the plus sign. By giving the rule a name, the following rules apply:

In the “Apply this rule if” condition, “the sender is” is selected and added to the Test account.

In the “Do the following” action, the option “Delete the message without notifying anyone” is selected.

Click More Options to display the Exception field.

The “Except if” condition is activated by “The recipient> the address includes any of these words” and is saved by entering the “[e-mail]” address.
