Use Retro Scan to check whether your current email security provider has missed any threats. Cloudflare scans up to 14 days of emails in your Microsoft 365 mailbox and generates a report of malicious messages. Once the scan is complete, you will receive an email notification with a link to the report.
To start a free scan:
- Log in to Cloudflare One ↗.
- Select Email security > Overview.
- Select Start a free scan > Generate report.
- Enable your Microsoft integration. Once you have enabled your Microsoft integration, you will be redirected to a page where you will add your domains and specify your current email security system.
- Generate Retro Scan report:
- Connect domains: Select at least one domain from your integration, then select Continue.
- Select current solution: Select the email security tool you are currently using, then select Continue.
- Review details: Confirm the domain and current solution you selected, then select Continue. You will receive an email notification once the report is ready.
- When you receive the notification email, select the link to view the full report.
- On the Cloudflare dashboard, select View report.
The dashboard will display Overview and Details pages.
The Overview page shows a summary of the scan results across your selected domains, including:
- Disposition evaluation, the verdict assigned to each scanned message (for example: malicious, suspicious, or spam)
- Malicious threat types
- Malicious targets, the top recipients targeted by malicious messages
- Malicious threat origins
The Details page lists up to 1,000 emails that were assigned a disposition during the scan. Select any email to review details about the message.
