I'm a little confused at this point. I have set up Exchange 2013 on a Windows 2012 Standard installation.
I have added users to domainname.local and have assigned them their real email addresses email@example.com in the Active Directory. I have created a mailbox for each user on the Exchange 2013 server.
But, I have not seen how to connect Exchange to the internet (domain name and MX records are hosted at GoDaddy).
I have been told that their old server used MAPI Exchange connections and that SMTP and POP were never set up on the old Exchange 2003 (in SBS 2003). But a Google for MAPI and Exchange has not produced anything that I see as enabling the Exchange server to send and receive email via the internet.
I am also getting an error "an unknown error occurred, error code: 0x80070057" when I try and connect Outlook 2010 to the Exchange 2013 server.
What have I missed?
