Microsoft’s provided great, customisable training material for Lync. Download the Lync training intranet site and publish on your webserver, applying your own CSS to give them a look and feel consistent with the rest of your organisation.

If you don’t want to go to that effort, check out this link. From here you can drill down to individual pages that provide useful individual articles like:

• This one covers the basics
• This one goes into the audio device settings
• This one demonstrates how to setup Call Forward and Simultaneous Ring
• Here is how to transfer calls
• …and this is how to access voicemail from within Lync

If you’re a real glutton for punishment, this link is to the ENTIRE training download package – all 98M of it!
