Hi,

Please use Get-TransportAgent to check if verify that the Exchange anti-spam filter agents are enabled.

FPE or FSE may report an incorrect spam confidence level (SCL) rating if the Exchange anti-spam filter agents are enabled on a computer that is running Microsoft Exchange Server and has the HUB Transport or Edge server role. By default, Exchange stamps the SCL rating if the Exchange anti-spam filter agents are enabled. However, if the Exchange anti-spam filter agents are not updated to the most recent versions, the SCL ratings may be incorrect.

After you disable the Exchange anti-spam filter agents, you should verify that policies and exclusions are configured correctly in FPE or FSE.
