Norton Firewall now blocking email and calendar (possibly others) after 4.1 Update

After installing the updates vai AutoUpdate I can no longer access my email or Calendar servers. Disabling Firewall (an undesirable step) addressed this but the issue did not exist prior to the update. Attempting to allow application and service connections ( which were not required before) had no effect. I'm currently obliged to run without Firewall in order to be able to work.

 

Is anyone else seeing this\have a solution?
