Hello there, 
 Thank you for contacting the Sophos Community. 
 Once you have added the relay in the Exchange outbound Relay rule, make sure this is enabled and there is no other rule taking precedence. 
 Additionally, if your upstream router is acting as an MTA, you would need to either disable it or add the relay for Sophos too. Also, double check ports are open for your Exchange. 
 Regards,
