Office 365 (Outlook 2013 / 2016 / 2019 for Win) - Find a Message or Item with Instant Search
Need to find an important message in your crowded Inbox or folder? Instant Search helps you to quickly find items in Outlook. The Instant Search pane is always available in all of your Outlook folders, such as Mail, Calendar, and Tasks.
IMPORTANT: Instant Search shows the first 30 matches. You can get up to 250 results by clicking More, below the results.
1. Find the Search box. It’s at the top of your message list, as shown here:
2. To find a word that you know is in a message, or a message from a particular person, type the word or person's name (you can use first, last, and partial names) in the search box. Messages that contain the word or name you specified appear with the search text highlighted in the results.
3. Narrow your search results:
If you can’t find what you’re looking for, use the search tools on the ribbon to narrow down your search. When you are in the Search box, you can select a Scope option on the left side of the ribbon. The default search is your Current Mailbox but you may want to expand the search to include Subfolders or All Outlook Items. Once you decide your scope, you can then Refine your search further by selecting an option such as the subject line, the sender, or who it was sent to, for example.
4. To refine your search even further, you can click on the + More option in the Refine section of the ribbon and add as many additional search fields as you like.
5. When you’re finished, you can clear the search by clicking the X (Close Search) in the ribon.
