Hit highlighting

Last published : Oct 28, 2026
Hit highlighting visually identifies relevant terms in the item preview pane. It highlights terms that match the search criteria and terms associated with tags, helping you quickly scan the email content and locate relevant information. Highlighting applies to the subject line, message body, attachment name, and text or HTML preview of attachments. However, navigation between occurrences is available only within the message body.
Search terms are highlighted in orange, and terms associated with tags are highlighted in green. Hover over a highlighted term to determine whether it originated from a search query or a tag.
