I enabled Skype for Business users to communicate with other Skype users. However this does not work as expected so I am not sure if we are doing it wrong or communication between these two apps does not work as we expect it. When I send a message from Skype for business, I get it on my Skype Linux app, but I cannot reply. I see a message that messaging is not available. When I log into Skype web app I can see the message, but as of a few days ago, I cannot reply. When I log out of Skype web app and log back in, I see a message that I have to add again the Skype for business user. When I click on the add button, nothing happens and such user is seen as not available. Is there is a way to fix this?
