Microsoft Allow lists and Safe Senders

Because of some recent changes to Microsoft’s MSAllowList flag, Microsoft allow lists are not always honored by Secure Email Threat Defense if your organization allows individual users to configure allow lists in their mailbox and a message happens to fall in a user’s allow list.

If you want Secure Email Threat Defense to honor these settings, deselect the Apply policy to Microsoft Safe Sender messages check box on the Configuration > Global settings > Unwanted message analysis panel. Safe Sender flags are respected for Spam and Graymail verdicts, but are not respected for Malicious and Phishing verdicts. That is, Safe Sender messages with Spam or Graymail verdicts will not be remediated.
