The 38 new file extensions that will soon be banned in Outlook for the web include: "The newly blocked file types are rarely used, so most organizations will not be affected by the change," the Microsoft Exchange team said in an announcement yesterday.

Microsoft plans to expand the list of file extensions that are banned in Outlook for the web (previously known as Outlook Web Access (OWA)).
