Search in Outlook puts your results on top

This warning message only appears when Outlook detects the local search service (Windows Desktop Search) is not indexing Outlook content. This will only impact searches that fall back to local search. Instructions to index Outlook with Windows Desktop Search can be found here, https://support.office.com/en-us/article/fix-search-issues-by-rebuildling-your-instant-search-catalog-213a2728-0ef4-427a-9bb2-aed329a59b17

Exclusions are possible in Outlook today. Using the minus character (“-“) or NOT operator will exclude results that contain that keyword.

Placing multiple search terms in quotation marks will return results only when those keywords appear exactly as typed in the quotations including order. Example: “Outlook Features” will enforce that results must contain Outlook followed by Features. This is different then search for Outlook AND Features as that will return results that contain both keywords, but not necessarily side by side in that order. For more information on advanced keyword properties that Outlook search supports see: https://docs.microsoft.com/en-us/sharepoint/dev/general-development/keyword-query-language-kql-syntax-reference

Note: For an easier way of building advanced queries we recommend using Advanced Search over manually typing Keyword Query Language (KQL). In the new Search at Top experience Advanced Search can be found by clicking the scope selection drop down on the right side of the search box.
