Office 365 (Apple Mail) - Disabling Spam Filter
Apple Mail provides built-in junk mail filters designed to keep spam out of your inbox. These spam filters are automatically enabled, however, Office 365 provides server side spam/phishing filtering which could conflict with client side filters. It is therefore recommended that you disable this function as soon as possible so that there are no mail delivery issues. This document will provide you step-by-step instructions on how to manually disable your spam filter.
Important: Making this change will affect every account configured within Apple Mail.
