Using older versions of Outlook for Mac in business environments
Hi, I'm Diane and will be happy to help you today.
You aren't overlooking anything - it is a limitation of the new Outlook. Only server side rules are supported at this time. (and only in Microsoft 365 accounts.)
If the condition is the same - it is OR: from mary OR bob but if there are two different conditions, it is AND: from Mary AND wiith subject "Test".
Put together with the OR sample, it would be
From (mary OR bob) AND with subject "test".
If you need client-side rules, you need to use the legacy Outlook.
