How to enable add-ins and connectors in outlook

When used, add-ins provide you with additional features that you can take advantage of. Add-ins in Office 365 are programs or utilities that help you automate tasks when you view or create messages/events.

Why do I see add-ins in my inbox?

Microsoft has partnered with leading companies to build add-ins that help you get things done right from your inbox. Microsoft also provides developers the ability to create customized add-ins — which UW-Madison’s Office 365 team has taken advantage of.

How do the add-ins work?

Most add-ins have access only to the data in the email message or calendar event that you’re working in.​ Some of the add-ins are designed to work only in Outlook on the web. Others are designed to work in Outlook on the web and Outlook for Windows.​ You can have the add-in work in Outlook for Windows or later by installing it directly from the Office Store.​

All add-ins are validated by Microsoft, including those that you install from the Office Store. For more information, see the privacy statement and the terms and conditions section in the add-in’s consent form.

What are the default add-ins included in UW-Madison’s implementation of Office 365

Microsoft continues to make updates to the default set of add-ins whenever Outlook on the web is updated. As part of our implementation, we also continue to add add-in which we think would benefit the campus community. Currently, the following add-ins are active for all Office 365 users: Action Items, Bing Maps, Doodle, Report Spam, My Templates, Suggested Meetings, and Unsubscribe. To better understand and take advantage of any of these add-ins, go to “My add-ins”.

How do I use the add-ins?

Are add-ins supported?

Office 365 team will provide best effort support – any support beyond basic troubleshooting will be handled by the add-in vendor.

What happens if I select Disable in the Manage add-ins/Consent page?

If you select Disable, it’ll deactivate the add-in, and you won’t see or be able to use the add-in again.

If you change your mind later, you can enable the add-in anytime by going to Manage apps, in the Settings menu Settings icon. You can also enable the apps from the Office Store.

How do contextual add-ins work?

Outlook detects if an add-in requested keywords and entities, such as meeting suggestions or addresses, that are in your message, and it underlines them. Please note that Microsoft always safeguards your privacy and doesn’t attempt to read or comprehend your message. Even though you might see underlined text, no information is sent to the add-in.

Remember, the add-in can run only after you have given your consent to activate it and you selected the underlined text.

Does the add-in send my data to third-party service? If so, why?

An add-in might send data to its own service, but only to complete the task you’ve requested. For example, the Bing maps add-in might send information to the Bing online service in order to find the location you’ve requested. All add-ins are required to comply by their privacy policies and Microsoft standards. See the add-in privacy statement for more details.

Where can I get more information about an add-in, its ratings, and reviews?

Go to the Office Store, and search for the add-in you’re looking for. Then, select the add-in to find information such as its overview, requirements, ratings, and reviews.

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 Online admins can control whether users can install add-ins for Office.

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 might 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 Online admins have a number of controls available for managing add-ins and users’ access to them. Admins 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). Admins can also disable users from installing Office Store add-ins, and from installing add-ins on behalf of other users.

To install add-ins for some or all users in your organization, see Manage deployment of add-ins in the Microsoft 365 admin center
