365 AI Recipient Validation
Pre-send Outlook validation for potentially misdirected or sensitive Microsoft 365 email.
Relevant to Microsoft 365 users who need pre-send checks for recipients and sensitive email content.
Check recipients and content before email is sent
An email sent to the wrong recipient, a missing recipient or sensitive content can be difficult to correct once the message has left Outlook. Replying to a large distribution list can create similar risks.
365 AI Recipient Validation analyses outgoing email before sending and presents warnings in a side panel. Users can correct the message or proceed, while future warnings and suggestions adjust according to their responses. Email text and attachments are analysed locally in the Outlook client rather than being transmitted to Hornetsecurity servers.
Where 365 AI Recipient Validation is used
The add-on is used to check recipient selection before sending Microsoft 365 email, including messages where an expected recipient is absent or an unintended recipient is included. It also flags messages containing PII and replies addressed to large distribution lists. Administrators can review warning activity and configure scenarios, user exclusions and trusted external domains.
