Tenant Allow/Block list vs Mailbox level Safe Sender/Blocked Sender lists

Copper Contributor

Hi everyone,


I'm trying to confirm the order and precedence of Spam filtering, transport rules, and Outlook mailbox junk mail configurations made by a user.


The specific question, if I add a sender to the Tenant level Allow list, or if I configure a transport rule to bypass spam filtering for a specific sender, but the user has configured the Outlook Blocked Sender list to include this sender, will the email still end up in the users junk mail folder regardless of what I do at the Tenant Allow/Block list or Transport rule level?

Tenant level is on top of user rule, btw, user side can decide 'block sender' as their level which means redirect mail to Junk folder
