(Edit: Just a reminder, no matter the method you use to obtain this, don’t forget to run the back end SQL updates as seen with the Install-CsDatabase commands in this article: http://support.microsoft.com/kb/2809243, for those used to Lync 2010 this is run of the mill, but for those new to Lync, please keep this in mind!)
Chris over at emptymessage.com has written the most amazing PowerShell app I’ve seen in a long time. It’s called the Lync Environment Report Builder. There’s a single PowerShell utility (Get-LyncInfo.ps1) that you run against your Lync 2013 environment. That generates a ZIP archive for you. You can take that back with you wherever you go. When it’s documentation time, you have a couple more scripts you can run against it. The first is New-LyncEnvReport.ps1, this creates a document which can be opened in Word and is full of tables and information about your Lync environment. The second, which is the one that made my jaw drop is New-LyncEnvDiagram.ps1, this script will document your environment in Visio. This isn’t a shabby Visio either, it looks REALLY nice. This is an amazing tool from a brilliant mind! Thank you Chris!
