Yes, same issue - the snooper log doesn't show qosenabled status properly if you are using Skype for Business Online - only works with Server.

Hi Trent.

As I stated earlier in this thread, the CoS tag is not in the application layer, but in the network layer, so the application (and hence the Snooper log) has no idea this is happening on the Windows OS.

Without an ExpressRoute your received packets from Office 365 is not tagged this must then be done by your edge firewall or core switch based on a source address, source port and destination port combination.
