Junk mail blocking not working

Create an Outlook.com inbox rule using a stable characteristic of these messages, because blocking does not prevent delivery—it only moves messages from the exact blocked address or domain to Junk Email.^1^

Create a rule instead of blocking again

Since blocking the messages repeatedly has not worked:

1. Sign in to Outlook.com in a browser.
2. Select Settings → Mail → Rules.
3. Select Add new rule.
4. Give it a name, such as Remove Fuddruckers messages.
5. Under Add a condition, choose the most consistent characteristic available:
   • The actual sender address, if it remains constant; or
   • Stable words in the subject if the sender address changes.
6. Under Add an action, select Move to → Deleted Items.
7. Enable Stop processing more rules so a later rule cannot move the message elsewhere.
8. Select Save.

Outlook.com rules support multiple conditions, actions, and exceptions and are applied to incoming messages.^2^

Why the blocked entry may not match

test-order.fuddruckers.com must be the domain of the message’s actual From address for a domain block to match. It may instead be text shown in the message, part of a link, or associated with a changing sender address. Blocking one address will not catch messages sent from different addresses; a stable-pattern rule is the documented fallback for that situation.^3^

Also check where new messages arrive:

• Junk Email: The blocker is operating as designed. Blocked mail is still delivered but redirected to this folder.
• Inbox: Compare the actual From addresses on several messages. If they differ, use the rule above.
• Inbox with the same exact sender: Go to Settings → Mail → Junk email and check whether that address or domain is also under Safe senders and domains. Remove it there if present, because a safe entry conflicts with treating it as junk.

If all messages use exactly the same sender and subject, Sweep is another option: select one message, choose Sweep, and configure all current and future messages from that sender to go to Deleted Items.^4^
