Some attachments in items (such as e-mail messages or appointments) in Microsoft Outlook 2010 have restricted access. Files that have specific extensions can be categorized as Level 1 (the user cannot view the file) or Level 2 (the user can open the file after saving it to disk).

  This article is for IT Professionals. If you’re not an IT Professional, but want to learn more about how to share files that have restricted file types, see Blocked attachments in Outlook (https://go.microsoft.com/fwlink/p/?LinkId=188575).

By default, Outlook 2010 classifies several file types as Level 1 and blocks files that have those extensions from being received by users. As an administrator, you can use Group Policy to manage how a file type is categorized for e-mail attachment blocking. For example, you can change a file type categorization from Level 1 to Level 2 or create a list of Level 2 file types. There are no Level 2 file types by default. For more information, see Planejar configurações de anexo no Outlook 2010.

The following table lists Level 1 file types that are blocked under a default installation of Outlook 2010.
