Allowing secure interaction with Office 365 apps

Citrix Secure Mail, Citrix Secure Web, and Citrix Files offer the option of opening the MDX container to allow users to transfer docs and data to Microsoft Office 365 apps. You manage this capability for iOS and Android platforms through the open-in policies on the Endpoint Management console.

Once opened in a Microsoft app, data is no longer secured or encrypted in the MDX container. Consider the security implications before enabling this feature. Particularly, customers concerned with data loss prevention or who are subject to HIPAA or other strict compliance requirements should weigh the trade-offs of opening the container.
