I work as a consultant and activated a Skype for Business Basic licence.
In Skype on my PC, few weeks ago, I was asked if I want to use Teams. For testing purpose, I answered 'yes' and automatically Skype was removed and Teams installed. Unfortunately, for a Skype for Business video conference system, I need absolutely Skype (the appliance can't read Teams meeting).
I tried to setup co-existence value in the O365 admin panel, but on the organization wide and on the user setting, under Teams Upgrade, I got the information :
These settings for your organization have been set by Microsoft and can't be changed. Learn more.
How can I use Skype for Business again ?
This is important for my business.
