Onboarding Microsoft 365 - Outbound

Modified on Sat, 7 Sep at 4:20 PM

About onboarding Microsoft 365 - Outbound

You can configure Perception Point X-Ray to scan outgoing [outbound] emails to detect malicious file attachments and malicious URLs. This outbound functionality can be added to inbound Microsoft 365 [Inline and API] integrations - and is performed using the Microsoft API connection method.

Note:

You can add this functionality for scanning outbound email only if your organization is configured to scan incoming Microsoft 365 email - using either the Microsoft 365 - Inline or the Microsoft 365 API connection method.
Don't enable the outbound scanning functionality if scanning for inbound email is not yet enabled.
Outbound scanning is not available for Google Workspace or Microsoft Exchange [on-prem] integrations.

Scan results will appear in the Scans page. In the Scans page, you can click the Outbound email filter icon [] to show scan results for outbound email only.

There are two benefits of enabling outbound email scanning:

Prevents negative consequences to your organization's reputation that may result from sending out malicious emails.
Improves inbound detection.

There is no quarantine available for outbound email scanning.
Outbound scanning includes scanning for malicious content - not for spam.

Licensing: There are no additional licensing requirements for enabling outbound scanning.
