Microsoft Defender for Office 365-Find the Domain Name of the Trusted ARC Sealers from the Message Header

An email message internet header is a metadata set containing information about the sender, recipient, routing, and delivery of an email. It can help you find the domain name of the trusted ARC sealers. The domain name must match the domain specified in the d value of the ARC-Seal and ARC-Message-Signature headers in affected messages.

1.Double-click the email and select File.

2.Select Properties.

3.Select all Internet headers contents and copy.

4.Use the Message Header Analyzer tool to analyze the message header.
