Making Skype work properly with HTTPS inspection enabled featuring To Probe Bypass or Not To Probe Bypass

As suggested (By DWA AKA PhoneBoy) in the thread https://community.checkpoint.com/message/27675-re-https-inspection-probe-bypass-to-enable-or-not-to-... 

which discusses HTTPS inspection an general and getting Skype to work without resorting to destination based IP address overrides or disabling HTTPS inspection on 'Skype clients' (a rather impossible concept) in particular here is the document and CSV file which at the time of writing can be used to achieve this.

Hello

Has somebody managed to do Skype4B work completely with https inspection enabled?

I have tried all the bypass destination rules I have been able to find, based in this thread and in others:

- bypass rule by dst:ip (Microsoft's Office 365 IP address )-Updated via API

-bypass rules by dst application/site (one rule with normal hostnames and another with regular expressions)

SkypeFB connects and the calls, video and chat work.

But I can not make "File sharing" or screen sharing.They fail.

Of course it works when I disable https inspection for SkypeFB, but it does no look like a good solution, as I will disable https inspections for all traffic from the corporte users---making https outbound inspection a nonsense.

Any help would be appreciated!

Regards
