I've tried this every way I can think of. Scenario: you have an inbox with five emails, each from a different person: personA, personB, ... personE. My goal is to write a search query that excludes people and shows the remaining emails.
I can write positive queries like
from:personA OR from:personB, and the query returns a mixed bag of emails from personA and personB.
I've written the converse query
NOT (from:personA OR from:personB) and the query returns all emails including personA and personB. I've tried variants like
NOT from:personA AND NOT from:personB,
NOT from:personA OR NOT from:personB and nothing works.
If I reduce the query to exclude only one person, it works as expected. However, if I try to expand scope to exclude more than one it doesn't returned desired results. What am I missing?
