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.
