How do I allow end user 'blocked sender lists' to work even if the server manages spam filtering?

  • 772

Client filtering in Outlook 2010 is disabled when the server is managing spam filtering. Unfortunately I have a few high profile users that prefer to spam-block mailing lists rather than unsubscribe, so even though the email is not really spam they are upset that it is coming into their mailbox.

As seen here, I am not the first person to wrestle with this issue, and the suggested fix there (setting New-FseExtendedOption –Name CFAllowBlockedSenders –Value true) also failed to work for me.

Can anyone provide another possible fix? Thank you kindly.

  1. First, tell the high-profile users to stop being such crybabies: "Wah! I don't want to see these messages in my inbox but I don't want to take 15 seconds to click unsubscribe!"

    Or, next time you are working on their computer, click unsubscribe for them or send an unsubscribe email or whatever it takes.

    Or set up a rule in Outlook to auto-delete messages from that address.

    But the real answer is to tell them they're being ridiculous.

  2. Utilize Safelist aggregation.

    You can set the number of allowed blocked and safe senders on a per-mailbox basis with:

    Set-Mailbox [email protected] -MaxSafeSenders 100 -MaxBlockedSenders 500

    Check out "Configure Safelist Aggregation" on TechNet
