Outlook search is quite powerful in that it will find the search term inside the message body and inside the actual attachments (for example an attached PDF file or a text file inside an attached ZIP file)
However this can be a problem as the search can have many hits because of this, and there is no easy way of telling why it matched. Is there a way of doing any of these?:
- Configure Outlook to highlight the search term in the search results pane
- Export the matched message to a file and find the search term inside it with an external tool
