I am a newbie at deploying exchange. My first deployment was Exchange 2013 std edition. After all the configuration, exchange could not send email to both exchange users and external domain users.
Current setup uses smarthost with a 3rd party hosting company and the POP3 collector is Mapilab. Mapilab was able to fetch email from the POP3 server but exchange could not submit to exchange mailboxes. Same goes for the relay for the outbound mails.
I need urgent help. PLS HELP!
