Symantec Policies on Skype For Business & attachments

Hi Guys,

I am using DLP 14.6 MP2 and same on the clinets(14.6 MP2). I am not able to find a solution how to stop file sharing on Skype for external domains.

I have tried Allication monitoring, but it's not working, created policies but still having problems.

I have even tried to make a policy for cloud storage file movement monitoring via Application monitoring. But still not able to capture attachments.

Is Symnatec still support Skype for Business? have you tried to stop any kind of attachment on Skype?

Do I need to create a different policy? or do I need to change anything on Clinet monitoring side. I have attached the screen-shots for your reference.

Please answer... Your comments can Help me......

Thanks,

Sandeep
