My OS is Server 2012 I have setup and config Exchange Server 2013, problem is I cant send externally. I try to send to my self with admin email address it works fine but when trying to send to my gmail address my message stays on the draft after i refresh it goes to sent items (OWA) but did not receive. any idea with regards to my setup and configuration might be missing or misconfig? Help.

Have you configured an internet send connector? This would be a send connector with the * address space that is configured to route to a smart host or via DNS. If you check the queue viewer on your Exchange Server do you see your messages there with any error?

have you set up your send connectors properly and set up your DNS,MX record on you local dns as well as on your external domain. also allow 25 and 587 ports on your frewall 

Yes I set it up, heres another I email my internal using my gmail account  and i receive it and when i reply its fine it sends my email reply and i receive it to my gmail, but when i test by sending to gmail, i did'nt receive it why is that? it sends externally when I reply to a mail (GMAIL) but when i compose (send to gmail) it did'nt sends?

Hi,

Have you used Queue Viewer to check the queues? This message might be stuck in queue.

Please try to send email to other external domain to check this issue.

I suggest to use Get-MessageTrackingLog cmdlet to track this message
