Is it possible to connect to the Office365 server and use UCWA (ucwa.skype.com/) with Skype for Business now?
I want to use this example https://www.matthewproctor.com/Send-An-IM-With-UCWA-Creating-the-Application/ , but I do not know which server I can use to connect ...
It looks like this feature was announced at BUILD 2016 . There is documentation on how to run it here .
No, as indicated on the Wiki Wiki page here, or on the official website http://ucwa.skype.com
UCWA is not yet available for Office 365, but only for Lync / S4B local installation
