Users in the environment maintain Blocked Senders lists in their Outlook client. These emails are going to Quarantine instead of being dropped. End users receive Quarantine digests with these senders and it is a minor annoyance. Spam policy is to quarantine spam and high confidence spam however, a block rule should block not mark as spam..

I will not maintain a transport rule or tenant level block list as a workaround for this.

You have the block list in a spam filter policy? If so, what is "spam and bulk items" policy set to?

If your block list is somewhere else, where?

In Outlook, you can Block senders. I as an administrator would prefer users maintain their own Blocklists. Not sure how the spam filter policy interacts with Outlook blocked senders but i want Outlook blocked senders to get blocked and not go to quarantine

With that policy, you're giving them a lot of rope to hang themselves with. Quarantined items are recoverable.

Cant tell you how many times users have accidentally added a sender to the block list. Quarantining is best. Dont cost nuthin.

That is really hard to realize, since spam filtering in EOP runs before the actual mailbox/end user settings. You could configure a custom spam filter policy and select the action that "Move message to Junk Email folder", which works the same as the junk email blocked action in the Outlook, but it is meaningless in my opinion.

Configure your spam filter policies
