Finding messages in Outlook (advanced searching)
It is often difficult to come up with the right search using the Advanced Find feature in Outlook. Instead, you can enter logical expressions in the search area of Outlook.
Example
Given the search criteria:
Subject has either “ahs” or “Health” or “Applied Health Sciences”
Sent by either myself or otherperson
Sent to either myself or otherperson
Sent between January 15, 2020 and May 30, 2020
Enter the following into the search dialogue box at the top of the main Outlook window:
(Subject:ahs OR Subject:Health OR Subject:"Applied Health Sciences") AND (from:me@uwaterloo.ca OR otherperson@uwaterloo.ca OR to:me@uwaterloo.ca OR otherperson@uwaterloo.ca) AND (Sent: > 01/15/2020 AND Sent: < 05/30/2020)
Notes:
You would need to enter actual email addresses instead of me@uwaterloo.ca and otherperson@uwaterloo.ca
If you are searching for messages in the more distant past, the search may come up empty but then offer to search for more results on the server. Extending the search to messages on the server may find additional messages from the past. Outlook usually stores copies of messages locally for a few months (in the cache) and the search starts there.
