So I have Exchange 2013 setup. I have several aliases that I need to setup, but realized the email aliases are not forwarding to the external users emails (cox.net, hotmail.com). I just did a test with my gmail.com and hotmail.com email account.
Here is what I am doing. In Exchange Admin Center, click on the mailbox. Click on email address. Add the @gmail.com and select Email address type: SMTP
Then I try to send to @gmail.com, but I am not receiving the email. I tried with my @hotmail.com account and same issue. The email goes through to the email address for the local domain, but not any external emails.
I did not create a contact for my email, but in the past I’ve never had to with Exchange 2010. Is there some configuration I need to do for Exchange 2013?
I don’t get a bounce back, since the email goes through to the local domain email address.
