I’m currently working through a Lync cut-over for a customer to Office 365. As they are moving from a single on-premise Lync 2010 server and didn’t wish to go the hybrid route, we are running through a cut-over process for users. Ideally we would like to do this with no interruption to existing users (ie, updating DNS settings for all). As such, would like to manually configure the test users to point directly to Office 365 Lync Online/Skype for Business – preferably with as little hands on as possible. Thankfully, these settings can be configured in the registry. These registry keys to set can be found:
I am packaging these settings into the installer for SCCM deployment but this could easily be adjust using a GPO, script, etc.
