After working with my internal IT department, they've determined that the simple reason I cannot get to the Lync server from my home computer is because it is not a member of the domain. There are two solutions they proposed: join the domain, or VPN in. The former isn't really an option, and the latter is a solution I can make work (only connect when I really need to talk to someone; running all my traffic through the VPN is downright miserable).

The error I get when I connect is:

"There was a problem verifying the certificate from the server. Sign-in may be 
delayed while we retry the connection..."

more detailed error:

02/15/2013|18:05:57.470 1C58:C28 TRACE :: SECURE_SOCKET: security negotiation has completed, verifying server cert
02/15/2013|18:05:57.472 1C58:C28 ERROR :: SECURE_SOCKET: negotiation failed

02/15/2013|18:05:57.472 1C58:13D0 TRACE :: CSIPTransportLayerSecurity::Shutdown - [0x065EA2F0]

As a developer, this looks like a different version of the SSL errors I get when I visit a website that's using a misnamed certificate. With that thinking, I went ahead and VPNed in, grabbed the certificate it presented me with and accepted it. Then I added it into my trusted CAs just to be sure. I was really hoping this would work, but results in the same error.

Anyone played this game before? Is there a workaround?

You may want to check with your IT Department to see if you need to install a Cert to talk to your exchange server. Also, try inputting your company's Lync server in the "Advanced" options when you access the Lync settings. Hope this helps.
