Ok so I got it working now with the primary smtp address. I re-setup the topology (primary SIP is user@domain.com) and made the DNS changes. <br />
<br />
I can now search for users through the address book correctly. <br />
<br />
With that though, I can no longer view the Presence of the user &quot;Presence Unknown&quot;

Maybe the problem is that cached address book on clients is not synced yet.<br />
Changes needs time to propagate to address books on clients. <br />
<br />
You can speed up things a little bit:<br />

Hello, <br />
<br />
I have installed Lync 2013 standard and all is good though looking for some direction. <br />
<br />
My internal domain is Domain.local which is making it an issue when I want to message someone. As it looks at the users email address which is domain.com. <br />
<br />
If I message someone and search for MrX@domain.local it works fine. Though if I message someone searching the address book... mrx@domain.com it fails to deliver or verify their presence.

Instant messaging (IM) is a type of online chat that offers real-time text transmission over the Internet. A LAN messenger operates in a similar way over a local area network. More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat. Non-IM types of chat include multicast transmission, usually referred to as "chat rooms". Depending on the IM protocol, the technical architecture can be peer-to-peer (direct point-to-point transmission) or client-server (a central server retransmits messages from the sender to the communication device).

Chat / IM

Telecommunication occurs when the exchange of information between two or more entities (communication) includes the use of technology. Communication technology uses channels to transmit information (as electrical signals), either over a physical medium (such as signal cables), or in the form of electromagnetic waves. The word is often used in its plural form, telecommunications, because it involves many different technologies.

Telecommunications
