Hi,

I am trying to configure a Fortigate 110C to block Skype traffic from exiting the LAN. All attempts to use application control to block P2p/Skype and apply that to a firewall protection profile have failed. The OS is 4.0 MR 1 Patch 6.

Configure the application control to block skype. Assign it to the protection profile of the policy that you want to block.
You MUST clear all sessions of the policy before it will work. Disable and re-enable the firewall policy (make sure you won't be disconnecting yourself) OR restart the firewall. I tested on a Fortigate 80C 4.0 MR1 Patch 4 and confirmed it.
If that doesn't work let me know.
