Once the AI Recipient Validation service has been set up for an organization, the AI Recipient Validation add-in appears in the Outlook applications of the organization's users.
The add-in is supported by several Outlook applications (Please see our System Requirements page for a list of supported Outlook Applications) and can only be used for primary mailboxes.
The add-in runs in the background and checks the emails that a user wants to send, checking new emails, a forwarded emails and replies to a received email.
The email is checked against all Warning Scenarios and if there is a matched warning then the add-in issues a warning as soon as the user tries to send the email. The user can then decide whether to edit the email again or send it despite the warning.
When checking emails, the add-in pulls data from the organization's relationship database. The relationship database is created during the AI Recipient Validation service setup, starting from data from the Microsoft 365 organization on email traffic for the past 6 months. During the use of the service, the relationship database is continuously expanded and updated. This way, the AI Recipient Validation add-in learns and the warnings become more and more reliable.
