I am running MacOS Sierra 10.12.6 and I wanted to create a basic rule that would look for the word "Monitoring" in a message subject and move it to a "Monitoring" mailbox if it was found. I created this rule and nothing happened to either my existing messages or new incoming messages.
When I select a message and click "Apply Rules" nothing happens. I deleted all other rules to be sure that nothing was preventing other rules from being applied - and even with my rule as the only rule available messages are not moved under any circumstances.
What do I need to do to get my rules to work?
