You may know how to Search in Outlook (type any word in the "Search Current Mailbox" textbox), but did you know that you can refine your search? Maybe you only want e-mails that have an attachment, or have the word "party" in the subject line. Here are some of the ways you can filter your search results: From: filters your search results to only show messages sent by a specific person. For example, you can search for all the messages sent by Sara. Subject: filters your search results based on the subject line of the email. For example, you can search for all the messages that have the keyword “report” in the subject line. Has Attachments: gives you all the messages that contain an attachment. This Week: choose a time frame to narrow your search results based on the time you received a message. Learn more about refining Outlook searches here.
