Ok thanks. I have read all about that and don’t really understand what has been removed or what the new protection involves.

But in any case, it doesn’t answer my question : Why are quarantined email still appearing in my inbox ?

If Norton is quarantining an email, it is detecting what it feels is some malicious content in that email. It is not able to block those emails from being sent to you. It can only deal with it when it gets to your computer.

Yes, I understand that but I thought they were sent to quarantine (which they are) and not to my inbox as well.

What is quarantine if it’s not a safe depository to move them to instead of my inbox where I could still open them if I were foolish enough ?

@Rufford155 The issue is you shouldn’t open them and not be foolish enough to chance what issues that may present. Within your e-mail client have to marked these senders as spam and blocked them at those settings? If not they are returning for that reason, Norton just continues to quarantine. There is no longer a spam folder for Norton to send spam to in Outlook.

I have not opened any of them but I have opened the Message Options dialogue to find the sender’s address. I block the senders which moves them to my Junk folder from where I can permanently delete them from time to time. They are not repeated, they come from different addresses although sometimes with the same From name and/or Subject line.

It’s perfectly obvious they are spam without any help from Norton.

It’s just a nuisance that I have to delete them manually from my Outlook Inbox>Junk AND from Norton’s quarantine.

I did the latter a day ago and there were 65 that all came within the last two weeks.

My email address is not a common one so someone has leaked it recently I think.

My wife has been visiting several health/wellness/diet type sites so I suspect one of them but she is upset if I suggest it.

The good news is that none have come today -yet.

Curious, what e-mail client are you using?

That is why you are still getting those emails in your inbox. The email address you blocked is different from the ones getting in. Depending on how you set up the spam filters, the username is not enough information for a filter to detect the spam. A new email address just gets by the filters.

SoulAsylum : Outlook (classic) within Microsoft 365.

peterweb : I thought if Norton put them in quarantine, they wouldn’t go anywhere else !

Here is some AI suggestions for you to possibly help:

AI Overview

To block a spam domain in Outlook Classic (part of Office 365) using wildcards, you typically add just the domain name (e.g.,

spamdomain.com) or use *@domain.com in the Junk Email Options’ Blocked Senders list, but for more advanced wildcard blocking (like *.spamdomain.com) or complex rules, you often need to use Mail Flow Rules (Transport Rules) in the Exchange Admin Center (EAC), especially for subdomains or patterns, as the Outlook client’s list has simpler matching.

Method 1: Simple Domain Block (Outlook Client)

This works for the whole domain but doesn’t use special wildcard syntax in the client’s Junk Settings.

  1. Open Junk E-mail Options: In Outlook Classic, go to the Home tab, click Junk, then Junk E-mail Options.
  2. Add to Blocked Senders: Go to the Blocked Senders tab and click Add.
  3. Enter Domain: Type the domain name (e.g., spamdomain.com) and click OK, then Apply/OK.

Method 2: Wildcard Blocking (Mail Flow Rule - Admin Needed)

This is best for blocking subdomains (e.g., *.spamdomain.com) and requires admin access to the Exchange Admin Center (EAC).

  1. Go to Exchange Admin Center: Navigate to the Microsoft 365 admin center and open the Exchange Admin Center (EAC).
  2. Create a Mail Flow Rule: Go to Mail flow > Rules and click Add a rule, then Create a new rule.
  3. Set Conditions:
  • Name the rule (e.g., “Block Spam Domain”).
  • Under “Apply this rule if…”, choose The sender > domain is… and add spamdomain.com to catch all emails from that domain.
  • For subdomains, you might need to use the syntax *.spamdomain.com or add a separate condition for the subdomain, as direct wildcard support in the client is limited.
  1. Set Actions: Under “Do the following…”, select Block the message > delete the message or Reject the message and include an explanation.
  2. Save the Rule: Review and save the rule. It should be active within minutes.

Key Takeaway

For basic domain blocking in your Outlook client, just enter the domain name. For advanced wildcard blocking of subdomains (like *.example.com), you must use Mail Flow Rules (Transport Rules) in the Exchange Admin Center.
