Important: due to changes in Microsoft policies, we can no longer set up federation with consumer Skype for our customers in the shared environment. Customers hosted on dedicated platforms continue to have this functionality enabled until further notice.

In order to be able to add regular Skype users as your Skype For Business contacts, you need to submit Skype For Business Federation request.

Note: there are currently some issues with Skype For Business and Consumer Skype federation. Read the Knowledge Base article on Skype For Business And Consumer Skype Federation Known Issues for more information
