Disable IM for a Skype for Business User

Recently there was a requirement to disable a user/machine from sending IM’s on Skype for Business.

This can be done quite easily with the below registry key on the users machine:

  • Open Command Prompt as an Admin
  • Run reg add HKLM\Software\Policies\Microsoft\Office\16.0\Lync /v DisableIM /t REG_DWORD /d 1 /f
  • Restart Skype client

The User/Machine will no longer have the functionality to IM ?
