I have a .NET Bot Bot platform created using the template and tested on other channels and on the toolbar.
I added the Skype for Business channel and executed PowerShell cmdlets for my tenant. However, I constantly get the response "Error contacting the target user."
I looked into the Bot Framework toolbar for problems, and the problem is that the Bot Framework returns 401 Unauthorized from my code. Remember that this works well in other channels.
Suspecting a problem with how Skype for Business transmits (or does not pass) authentication tokens, I commented out the BotAuthentication decoder. Suddenly everything is working fine. Therefore, I think that there is a problem with the Skype for Business channel and how it transmits authentication data, since this situation is clearly not ideal.
