What is apps for Office?
Developers use apps for Office to create engaging new consumer and enterprise experiences that run within supported Office 2013 applications by using the power of the web and standard web technologies such as HTML5, XML, CSS3, JavaScript, and REST APIs.
An app for Office is basically a webpage that is hosted inside an Office client application. You can use apps to extend the functionality of a document, email message, meeting request, or appointment. Apps can run in multiple environments and clients. These include rich Office desktop clients, Office Web Apps, mobile browsers, and also on-premises and in the cloud. Developers can publish apps to the Office Store or to an onsite catalog, where they can be available to users from their Office 2013 applications. As the IT Administrator of your organization, you can control how the apps for Office become available to users.
Anatomy of an app for Office
The basic components of an app for Office are an XML manifest file and a webpage. The manifest defines various settings and points to the webpage that implements the app UI and custom logic, as shown in the following figure.
Manifest + webpage = an app for Office
The manifest specifies settings and capabilities of the app, such as the following:
-
The URL of the webpage that implements the app UI and programming logic.
-
The app display name, description, ID, version, and default locale.
-
Whether the app can be shown as a task pane, in line with document content, or started contextually in an email message, meeting request, or appointment.
-
The kinds of client applications (including rich and Web App clients) that an app supports.
-
The permission level and data access requirements for the app.
Types of apps for Office
The three basic types of apps for Office are task pane, content, and mail apps for Outlook.
Task pane apps
Task pane apps enable users to see the app for Office side-by-side with an Office document, and provide app for Office developers with the opportunity to supply contextual information and functionality to enhance the document viewing and authoring experience. For example, a task pane app can look up and retrieve product information from a web service, based on the product name or part number that a user selects in a document. An example of a task pane app for Word 2013 that uses the Bing Translator service is shown in the following figure.

Content apps
Content apps integrate web-based features as content that can be shown in line with the document. Content apps enable users to integrate rich, web-based data visualizations, embedded media such as integrating a YouTube video player or a picture gallery as part of a document, and also other external content. The following figure shows an example of a content app for Excel 2013 that uses a web service to generate a geographical sales heat map.

Mail apps for Outlook
Mail apps for Outlook are displayed next to the currently viewed Outlook items: email message, meeting request, meeting response, meeting cancellation, or appointment. They can access contextual information from the item and use that data to access additional information about the server and from web services to create compelling user experiences. In most cases, a mail app for Outlook runs without modification on the Outlook 2013 rich client and Outlook Web App for Exchange Server 2013. This user experience is seamless, whether on the desktop, the web, or on tablet and mobile devices.

The mail apps for Outlook require Exchange Server 2013. POP and IMAP email accounts are not supported. |
The following figure shows an example of a mail app for Outlook that uses the Bing Maps service.

Supported applications for apps for Office
One big benefit of apps for Office is that they can be supported both on Office 2013 rich clients and some corresponding Web Apps. To the developer, this means that, in many scenarios, they do not have to create separate apps for different environments or applications. To the user, it means a consistent user experience across the desktop and web browser. And for the IT Professional, it means that it’s easier to manage apps for Office across environments and applications.
For task pane apps, this means the same app can run on Excel 2013, Excel Web App, Word 2013, and Project 2013. For apps for Outlook, it means that the same app can work for Outlook 2013 on the desktop, tablet, and mobile devices.

Privacy and security for apps for Office
Privacy and security for apps for Office are covered in the following two MSDN topics:
See Using Group Policy to manage how users can install and use apps for Office to learn more about the Group Policy settings that can help you manage privacy and security for apps for Office.
Managing access to apps for Office
As the IT Administrator of your organization, you can control how the apps for Office become available to users. You can choose the type of hosting option that's appropriate for your organization. For example, if you don’t want users to access apps for Office from the Office Store, you can disable that capability by using Group Policy. Then, you can make apps for Office available to users by hosting them internally in a SharePoint App Catalog, an Exchange catalog, or a file catalog share. These distribution methods are described in the following sections.
Supported distribution points for apps for Office
After an app for Office is created by a developer, the developer can decide how to publish it so that it is available to the users within your organization. In Office 2013, the following distribution points are supported for publishing apps for Office:
-
Office Store Hosted and regulated by Microsoft, the Office Store is where developers around the world can publish and sell their custom Office solutions. End users and IT professionals can download these custom Office solutions for personal or corporate use. Office Store handles the consumer download experience from discovery to purchase, upgrades, and updates.
-
SharePoint App Catalog For task pane and content apps, IT departments can deploy private app catalogs to provide the same app acquisition experience that the Office Store provides. This new catalog and development platform enables IT departments to use a streamlined method to distribute apps for Office and SharePoint to managed users from a central location.
App Catalog is available to all SharePoint customers (including Office 365 and SharePoint on-premises). App Catalog enables publishing and administration of both internally created apps and apps that are available in the Office Store and licensed for corporate use. For more information, see Manage the App Catalog in SharePoint 2013.
-
Exchange catalog This is a private catalog that is managed by an Exchange administrator for mail apps that are available to users of the Exchange Server on which it resides. It enables publication and administration of corporate mail apps, such as internally created apps and apps that are available in the Office Store and licensed for corporate use.
-
File-based app catalog IT departments and developers can deploy task pane and content apps to a central file share, where the manifest files will be stored and managed. Users can then obtain apps by specifying this file share as a trusted catalog, or an IT administrator can configure this file share as a trusted catalog by using Group Policy.
Using Group Policy to manage how users can install and use apps for Office
You can manage and enforce apps for Office settings by using Group Policy settings that are available in the Office 2013 Administrative Template files (ADMX/ADML) and Office Customization Tool. The settings are found under User Configuration\Administrative Templates\Microsoft Office 2013\Security Settings\Trust Center\Trusted Catalogs. The OCT settings are in corresponding locations on the Modify user settings page of the OCT.
The following table describes the Group Policy settings that manage apps for Office.
Group Policy settings for apps for Office
| Setting name | Description |
|---|---|
|

|
Default Shared Folder Location |
Allows you to set the URL for the Shared Folder from which users can insert apps into their Office documents. |
|
Default SharePoint Catalog Location |
Allows you to set the location of the SharePoint Catalog that is designated as Default. The apps for Office that are contained in the Default Catalog can be inserted into Office documents by users. |
|
