So the scenario is: I start conversation on MS Teams with someone external who uses skype for business. I have MS Teams application and OWA opened on my machine. When a person replies - I see the reply on the OWA! - in this Skype OWA addon, instead of the MS Teams application - is there any way to redirect such messages to MS Teams instead of OWA?
You must be in Teams only mode for external chats to land in Teams. Otherwise they all go to Skype for business. Aka owa sonce Skype loads in the top right in owa so you get those there since I would bet some money you are probably on islands coexistence mode ;).
