    Hi,

    Looks like its due to anonymous relay configuration. Please add the sender email address to "Safe Senders" list in the Junk email option in Outlook if its for few users. If its for all users, create a transport rule to set SCL value -1 for that sender address.

    Hi anonymous user,

    Agree with AshokM that you can try setting the SCL to Bypass spam filtering via the mail flow rules and see how it goes. Or you can try adding the email address of the sender to the Safe Senders list and Safe Recipients list on all user mailboxes: 

    Get-Mailbox -RecipientTypeDetails UserMailbox | Set-MailboxJunkEmailConfiguration -TrustedSendersAndDomains @{Add="test@abc.com"}
