I found this posting from Dmitry with an OCS 2007 PowerShell solution and thought I would pass it on - if you have other solutions please comment with links. Since Dmitry's post does a really good job of showing the UI, I won't repeat it here.

<p>It is free, based on PowerShell, and has a lot of functionality not present in the native OCS MMC. Check it out here. Originally spotted here. To use this, you will need PowerShell, PowerGui, and the OCS PowerPack.</p>
