The Message Bar in Office applications is used to identify security issues, such as unsigned macros or potentially unsafe add-ins. When such issues are detected, the application disables the unsafe feature or content and displays the Message Bar at the top of the active window. The Message Bar informs the users about the nature of the security issue and, in some cases, provides the users with an option to enable the potentially unsafe feature or content, which could harm the user's computer. By default, if an Office application detects a security issue, the Message Bar is displayed. However, this configuration can be modified by users in the Trust Center.

Although this feature does not intentionally collect personal information, some of the content sent could include items that were marked as spelling or grammar errors, such as proper names and account numbers. However, any numbers such as account numbers, street addresses, and phone numbers are converted to zeroes when the data is collected.

An XML expansion pack is the group of files that constitutes a Smart Document in Excel and Word. One or more components that provide the logic needed for a Smart Document are packaged by using an XML expansion pack. These components can include any type of file, including XML schemas, Extensible Stylesheet Language Transforms (XSLTs), dynamic-link libraries (DLLs), and image files, as well as additional XML files, HTML files, Word files, Excel files, and text files. The key component to building an XML expansion pack is creating an XML expansion pack manifest file. By creating this file, the locations of all files that make up the XML expansion pack are specified, as well as information that instructs Office 2013 how to set up the files for the Smart Document. The XML expansion pack can also contain information about how to set up other files, such as how to install and register a COM object required by the XML expansion pack. XML expansion packs can be used to initialize and load malicious code, which might affect the stability of a computer and lead to data loss.

ActiveX controls are Component Object Model (COM) objects and have unrestricted access to users' computers. ActiveX controls can access the local file system and change the registry settings of the operating system. If a malicious user repurposes an ActiveX control to take over a user's computer, the effect could be significant. To help improve security, ActiveX developers can mark controls as Safe For Initialization (SFI), which means that the developer states that the controls are safe to open and run and not capable of causing harm to any computers. If a control is not marked SFI, the control could adversely affect a computer--or it could mean the developers did not test the control in all situations and are not sure whether their control might be compromised at some future date. SFI controls run in safe mode, which limits their access to the computer. For example, a worksheet control can both read and write files when it is in unsafe mode, but perhaps only read from files when it is in safe mode. This functionality allows the control to be used in very powerful ways when safety is not important, but the control would still be safe for use in a Web page. If a control is not marked as SFI, it is marked Unsafe For Initialization (UFI), which means that it is capable of affecting a user's computer. If UFI ActiveX controls are loaded, they are always loaded in unsafe mode.System AdministratorInformation Assurance Officer

The "Office Feedback" tool, also called "Send-a-Smile", allows a user to click on an icon and send feedback to Microsoft. The "Office Feedback" Tool must be configured to be disabled. In the event that the Office Feedback Tool has not been configured correctly as disabled, this policy configures whether the uploading of screenshots via the tool is allowed and should also be disabled. Uploading screenshots to a commercial vendor from a DoD computer may unintentionally reveal configuration and/or FOUO content.System AdministratorInformation Assurance Officer

Microsoft Office includes the ability to roam settings for specific Office features amongst devices by storing this data in the cloud. This data includes user activity such as the list of most recently used documents as well as user preferences such as the Office theme. This policy setting controls whether this data is allowed to be stored in the cloud. If this policy setting is enabled, roaming settings are only stored locally and not synchronized to the Microsoft Office roaming settings web service. If this policy setting is disabled or not configured, roaming settings are synchronized with the Microsoft Office roaming settings web service and users can access their data from other devices.

Office Telemetry is a new compatibility monitoring framework. When an Office document or solution is loaded, used, closed, or raises an error in certain Office 2013 applications, the Office Telemetry application adds a record about the event to a local data store. Each record includes a description of the problem and a link to more information. Inventory and usage data is also tracked. The actual logging capability will be enabled, but this policy allows that data to be uploaded to a remote location which, if enabled, could pass information about the internal network and configuration to that remote site.System AdministratorInformation Assurance Officer
