I need to add a user to a "0nly senders in the following list" group under "Mail flow settings" and then "Message Delivery Restictions" so that user will be allowed to send e-mail to DL in exchange 2010 but receving below error.
"domain.com/microsoft Exchange System Objects/xx" isnt a group or an individual recepint" where xx is a name of another generac account which I have no idea why is complaining about it. Account is active and in use.
Can you please to resolve this? thanks
