I have the need to have all emails that do not come from my company's domain route into a certain folder in Outlook. The purpose is to give me a higher state of alert that an email was not sent through our mail system from an internal address. FYI, we have a few domains, so I would want to whitelist those. I know I can create rules for emails from a specific person, but I can't exactly add the entire internet to the junk mail/block sender list.
Is it possible to create a rule in Outlook to accomplish this?
