There are several places on the web that consolidate lots of Lync 2010 resources, but I’m yet to find one that seems to have everything I need to lay my hands on when I build a new Lync 2010. Here’s mine. I hope it’s of use to you. If you find any tools that you think are missing from this list, please let me know.

Here are my other toolkits

• Skype for Business 2019 Resource Toolkit.
• Skype for Business 2015 Resource Toolkit.
• Lync 2013 Resource Toolkit.

I’m no longer regularly updating this page. Can we chat about a Skype for Business upgrade instead?

Third-party tools and utils

• Batch file to set the GalDownloadInitialDelay to 0
• EHLO World’s fantastic “get-csconnections.ps1” script. Audit client versions, see who’s connected to what FE & more.
• Curtis Johnstone’s “MOCLogin”, now “The OCS & Lync Sign-In Troubleshooting Tool V3.0”
• Stumper’s “Find Lync Versions” – reports who’s patched and who’s not
• Notepad++. Essential for viewing logs from the UX2000, and has a great file comparison feature too!
• 7-zip. The only archiver you ever need. Opens ISOs & can split GIANT log files into manageable chunks
• Goldwave – brilliant audio editing software. You’ll need this to neaten your RGS and AA recordings or perhaps resample the customer-provided MOH file to a supported format. The best $50 you’ll spend for a while!
• Chad McGreanor’s walk-through on requesting a cert for TMG
• Event Zero’s “Big Boss” web-based app will generate a test call to you. Alternatively, try their Federation Tester
• Johan Veldhuis has created a great PowerShell-based GUI wrapper for SEFAUtil. It works for both the Lync 2010 and 2013 releases
• Chris Wright’s AD Photo Edit tool. Highly commended. It probably annoys the pants off the commercial software operations that such a great util can be had for free!
• Curtis Johnstone shows how to establish a remote powershell session.

• Elyza – a Lync implementation of Weizenbaum’s 1966 “ELIZA” + useful Lync test and demo tool
