When troubleshooting email delivery issues in Salesforce, it is often necessary to capture and share email message headers with Salesforce Support. Email message headers contain metadata about the email's routing path, timestamps, sender authentication records (such as SPF and DKIM), and server hops. This information helps Salesforce Support diagnose why emails may be delayed, blocked, or not delivered as expected.
This article provides steps for capturing message headers in Microsoft Outlook on desktop and Outlook on the Web (OWA).
'View internet message headers' on the Microsoft Support site
'Message Header Analyzer' on the Microsoft Support site
Note: If you are not using Microsoft Outlook, refer to your email software's help documentation for instructions on retrieving message headers.
