Hi @Frank Macintosh ,
Welcome to our forum!
body:(Alice AND Bob AND DesiredWord) AND (NOT "Don't want this phrase")
Based on my test on this condition, it works. Steps are as following:
1.Cilck the Search bar > click the drop-down arrow > enter "(Alice AND Bob AND DesiredWord) AND (NOT "Don't want this phrase")" in the box after Body:
2.Select the appropriate range (e.g. I select the Current Folder) and click Search, then emails that match your criteria will then appear in the search list:
3.In addition, I added an attachment containing "(DesiredWord)" to the test email, which was not searched with the same search conditions.
4.Considering that you may try to enter "body:(Alice AND Bob AND DesiredWord) AND (NOT "Don't want this phrase")" directly in Search bar, i tried too and get the correct search result.
To further confirm if your issue is related to your current search settings, please try to change the scope of your search and check if there're any differences.
On the basis of the above, it is recommended that you refer to this article and try to do some search-related troubleshooting: Outlook search returns incomplete results.
Is there still no such reference document?
As far as Outlook clients are concerned, there is an official document detailing how to use the Search feature: How to search in Outlook.
Hope the above help!
