Add-ins for Outlook in Exchange Server
Applies to: Exchange Server 2013 and 2016
Add-ins for Outlook are applications that extend the usefulness of Outlook clients by adding information or tools that your users can use without having to leave Outlook. Add-ins are built by third-party developers and can be installed either from a file or URL or from the Office Store. By default, all users can install add-ins. Exchange administrators can use Roles to control users' ability to install add-ins.
For information about add-ins for Outlook from an end-user perspective, check out Installed add-ins. The topic provides an overview of the add-ins and also shows you some of the add-ins for Outlook that may be installed by default.
Office Store add-ins and custom add-ins
Outlook clients supports a variety of add-ins that are available through the Office Store. Outlook also supports custom add-ins that you can create and distribute to users in your organization.
Access to the Office Store isn't supported for mailboxes or organizations in specific regions. If you don't see Add from the Office Store as an option in the Exchange admin center under Organization > Add-ins > New , you may be able to install an add-in for Outlook from a URL or file location. For more information, contact your service provider.
Some add-ins for Outlook are installed by default. Default add-ins for Outlook only activate on English language content. For example, German postal addresses in the message body won't activate the Bing Maps add-in.
Add-in access and installation
By default, all users can install and remove add-ins. Exchange administrators have a number of controls available for managing add-ins and users' access to them. Administrators can disable users from installing add-ins that are not downloaded from the Office Store (instead they are "side loaded" from a file or URL). Administrators can also disable users from installing Office Store add-ins, and from installing add-ins on behalf of other users. It is also possible to assign users to a role that allows them to install add-ins for your organization or for a subset of users in your organization.
To prevent users from installing an add-in that isn't from the Office Store, remove the My Custom Apps role from them. To disable users from installing add-ins from the Office Store, remove the My Marketplace Apps role from them. For more details, see Specify the administrators and users who can install and manage add-ins for Outlook.
To install add-ins for some or all users in your organization, see Install or remove add-ins for Outlook for your organization.
If required, you can limit availability of an add-in to specific users in your organization. For more information, see Manage user access to add-ins for Outlook.
Common administrative tasks with add-ins for Outlook
There are a couple of common scenarios that Exchange administrators manage in their organizations.
If you want to prevent end users from installing add-ins for Outlook on all Outlook clients, make the following changes to roles in the Exchange admin center:
To prevent users from installing Office Store add-ins, remove the My Marketplace role from them.
To prevent users from loading add-ins from sources other than the Office Store, remove the My Custom Apps role from them.
To prevent users from installing all add-ins, remove both of the above roles from them.
See Specify the administrators and users who can install and manage add-ins for Outlook for more information.
If your end users are currently able to access add-ins and you want to remove that access, use the Get-App cmdlet in the Exchange Management Shell to see which add-ins each user has installed, and then use the Remove-App cmdlet to remove any add-ins from one or more users.

Allow administrators and users to install add-ins
You can specify which administrators in your organization have permission to install and manage add-ins for Outlook. You can also specify which users in your organization have permission to install and manage add-ins for their own use.
