Exchange Online Mail Flow Rules to stop supporting DLP-related rules, conditions, and actions

lukesrees Depends on your rule - if the rule uses any of the mentioned predicates above then that rule won't work come mid-November (early to mid-next week). If you're using something else for your profanity list like a simple expression check using the condition "SubjectOrBodyContainsWords" (aka "The subject or body includes any of these words" in the EAC UI) then it won't be affected. That said, you might consider just moving it to DLP along with your outbound DLP rule. Purview DLP supports both outbound and inbound mail flows (e.g. use Content is received from. . .People outside my organization).
