Could be MTU problems especially if ICMP is filtered. Can you ping with DF set at 1500 (raw packet) or 1472 (payload) to the app store?
Check the MTU like jayh mentioned.
As far as what ports are used for the Windows AppStore, I was not able to find anything in a quick internet search, but you might want to contact Microsoft or check out their help pages.
You could also use a packet capture on a client device on a different network. That should allow you see what ports are in use. The Windows App store may use standard protocols like FTP, SCP, HTTP, etc. or they may use some proprietary protocols.
Once you have determined the ports, can you add them to your user Roles on the BSC. The roles are the firewall for the clients on the BSC.
