I’d love to give credit by name but I only have the name “stumper” to thank for a great OCS/Lync tool. Those of you who spent much time managing OCS environments are probably familiar with the Client Version Summary that was easily accessible in the OCS admin tool. Unfortunately the only way to gather equivalent information in Lync was to write the appropriate SQL queries to do so. However, our friend stumper has written a nice, simple app to get this information. You can even get the source code if you want to make changes. Here’s a link: https://www.stumper66.com/software/lync.html
Here’s an image of it from stumper’s site:
The summary tab is very handy to get a quick look at your client usage. In my case it was great to see how many users were still using MOC instead of Lync.
