Android Skype for Business issue with Exchange iApp

Thanks for the response. 1. I tried that with F5 support but I could not decrypt the output with ssldump tool. It appears I need to use a differen cipher in order to be able to do that. 2. What do you mean debug logs from the Skype for Android, how can I get that? 3. As I mentioned, EWS had Basic+NTLM enabled, which didn't work. When I changed to Basic only, it seemed to work partially but still gives an error. How did you eventually resolve your issues?
