How to enable a Domain Admin for Skype for Business

/ Perhaps you have seen the error message below when trying to enable a Domain Admin (not recommended) in the Skype for Business control panel.

You cannot use the Control Panel to users who belong to protected security groups. So your options are to either use Powershell as suggested in the error message or you could try this magical thing:

1. Open active directory users and computers
2. Enable the advanced features in the view menu
3. Search for the account which is in a protected security group
4. Go to Properties / Security / Advanced
5. Check the following box: Include inheritable permissions
6. Retry what you were doing in the Lync Control Panel

This great feature is still availlable in Lync Server 2013 and Skype for Business Server 2015.

Let’s build a text-to-speech message and forward the call to the reception for example:
