Changes to the way EOP moves email to Junk folder
Note: This change will only effect EOP customers with Exchange online mailboxes. EOP standalone customers with hybrid environments will have no impact.
Today EOP depends on the junk email rule to move spam/phish messages to a user’s Junk folder based on the spam confidence level set by EOP. Going forward EOP will use it’s own mailflow delivery agent to move malicious emails to the Junk folder depending on the policy set by security admins in Antispam policy. EOP will continue to honor the user safe sender/block sender preferences set in outlook just as the junk email rule does today.
