Re-posting the question "Outlook Rules - How to use "OR" boolean?", as there is no accepted answer there, and it was Outlook 2010 specific.
I'm using Outlook 2016 now, but still facing the very problem in that Outlook 2010 question:
It seems that Microsoft Outlook 2010 can only use the "AND" boolean when setting RULES. I find that very disturbing since even the lower end Windows Live Mail can use "OR".
- There is an answer that states, "for subject line you can use both AND / OR Operators", but that is not justified with any source.
- The OP is actually wanting to filter by sender or subject
- and I need filter rules for this sender or that sender
- Creating two separate rules can be, if otherwise impossible, the answer, but also note the following comment "At my work, there are so many lists and such that rule count is actually a problem. Outlook 2010 has a rather low rule number limit, so a reasonable filtering strategy would be nice."
