I have Exchange Server 2010 in my environment and I have the following problem with Distribution Lists.
I have created one Distribution List which includes email addresses from our company and external email addresses.
When I send from inside all works fine.
But when I send from outside the email received from inside users(email addresses of my domain) but never received from outside email addresses.
How can resolve this issue?
i have change this setting when create the group.But my problem isn't that users from outside can't send to distribution list. The problem is that in my distribution list i have email addresses from my company (@domain.com) and external email addresses (@gmail.com,@yahoo.com).
When a user from inside send to the Distribution List all works fine. When a user from outside send to the Distribution List, users from my company(@domain.com) which include in the Distribution List receive the email but user with external email addresses(@gmail.com,@yahoo.com) didn't receive the email.
