Is there a way Netskope could block CCI being exfiltrated through Microsoft Outlook 'Get Add-in'? When we attach a CCI document from Outlook to the dropbox Outlook extension, there should be some sort of web traffic generated. Any possible way or thoughts we could capture this traffic only to outlook and implement a Netskope block?

Good day, @arjun98854! The Microsoft Outlook desktop application is certificate pinned and cannot be inspected. If you wish to inspect sensitive data being sent through email (regardless of whether or not the user is using the Outlook app) talk to your account team about our Email DLP solution. If the data is being attached through a web browser, we can leverage real-time policy to inspect and take action.
