XG Firewall Policy blocks Office365 download and install

I put in the following exceptions, and was able to get the Office 365 to sucessfully complete:

^([A-Za-z0-9.-]*\.)?microsoft\.com/
^([A-Za-z0-9.-]*\.)?windowsupdate\.com/
^([A-Za-z0-9.-]*\.)?officecdn.microsoft.com.edgesuite.net/
^([A-Za-z0-9.-]*\.)?officecdn.microsoft\.com/
^([A-Za-z0-9.-]*\.)?windows\.com/

Initially I had just the officecdn.microsoft.com.edgesuite.net & officecde.microsoft.com urls in the exception. 
I had to add the other three to get it to work. 

Hope this helps.

And XG V18 will update those pattern automatically (Managed TLS List).
