There are two ways to fix this one is to create a public global DNS Cname record that points to the 0365 Lync service, this will work for both internal and external clients. Further if your firewall blocks access to public SRV DNS records the Lync client will fail to connect. Your corporate firewall needs to have outbound port 443 (for the STUN/TCP and PSOM/TLS protocols), 3478 (STUN/UDP) and 50000-59999 (RTP/UDP) open, as well as allow outbound connectivity to the *., *. and *. domains.

Setting up IM federation in Office 365 is easy but we’re waiting for integration with more IM networks. There’s also an option to enable IM federation with the Live Messenger network as well as Lync and Office Communications Server 2007 /2007 R2 implementations on premise. Lync Online lets you IM outside the organisation, the administrator can either enable federation with all other O365 tenants with the option to blacklist certain companies or only enable federation with selected companies. LWA offers IM and desktop sharing but there’s no audio and video support. There’s also a Lync Web App (LWA) that is supported in IE, Firefox and Safari which requires Silverlight.

The Lync client is a separate installation to Office Pro Plus and you need to run the Desktop Setup tool after its installation to configure settings. Unlike Live Messenger and Facebook this presence information is gathered from your Outlook calendar as well as when you manually set it. Just like most other IM clients you simply search the directory to add buddies and their presence is displayed.
