More information
The Previewer feature in Outlook uses the Protected View feature (also known as a sandbox). This feature was introduced in Microsoft Office 2010. In Windows 10, Windows 8.1, Windows 8, and Windows Server 2012, the Protected View feature has been improved in conjunction with the AppContainer feature. This provides stronger process isolation, and it also blocks network access from the sandbox. 

For more information about the Protected View feature, see Overview of security in Office 2013
