Why Native External Sender Callouts are Important for Your Business
In this digital age, businesses rely heavily on email to communicate with customers, partners, and vendors. Email is one of the primary channels of communication and businesses need to ensure that the emails they receive are from legitimate sources and not from malicious actors trying to exploit their systems.

Native external sender callouts are a feature of Exchange Online that allow administrators to verify sender identity when a message is sent from outside of their organization. This verification process is critical for ensuring that messages from external senders are from legitimate sources, and not from malicious actors who could be attempting to exploit the organization’s systems.

How Do Native External Sender Callouts Work?
Native external sender callouts work by sending an authentication request to the sending mail server. The authentication request includes information about the sender, such as their IP address, the date and time of the email, and the type of authentication used.

If the authentication request is successful, the mail server will respond with an authentication token. The authentication token is used to verify the sender’s identity. If the authentication token is valid, the message is delivered.

How to Set Up Native External Sender Callouts
Setting up native external sender callouts is simple and straightforward. All you need to do is log into your Exchange Online account and go to the Exchange Admin Center.

From there, go to the Mail Flow tab and click on the Connectors option. Then click on the + symbol to create a new connector.

Choose the type of connector you want to create—in this case, you’ll select “Native External Sender Callouts”.

You’ll then be asked to provide some basic information, such as the name of the connector, the type of authentication you want to use, and the IP addresses of the mail servers you want to send the authentication request to.

Once you’ve filled out the necessary information, click the “Save” button to create the connector.
