What is needed in order to use Skype For Business?
Basically, we'd like to use Skype For Business to share screens and chat between two persons in our company but our company is NOT using Office 365.
So we downloaded and installed Skype For Business. On the Sign In page, we see the message "Use the sign-in address for your organization - not a Skype Name or Microsoft account".
Please see attached screen shot.
What is the "sign-in address for your origanization"? How can we get it? Does this mean that we have to open an O365 account and be a subscriber?
