Actionable messages in Outlook and Office 365 Groups


Onboarding of new Actionable Messages providers with a Global scope is temporarily paused until Jun 30th, 2024 due to service upgrades. Existing Global scoped providers and onboarding of Organization and Test scope providers are not impacted. For more details, see Frequently asked questions for Actionable Messages.

Whether you are filling out a survey, approving an expense report, or updating a CRM sales opportunity, Actionable Messages enable you to take quick actions right from within Outlook. Developers can now embed actions in their emails or notifications, elevating user engagement with their services and increasing organizational productivity.

Office 365 provides two solutions to enhance productivity with Outlook Actionable Messages: actionable messages via email, and actionable messages via Office connectors.


Actionable messages are also available in Microsoft Teams. See Office connectors for Teams for more information.

User experience

Let's take a look at the end-to-end user experience for both an email-based and a connectors-based actionable message scenario.

Actionable messages via email: group membership request approval scenario

A Contoso employee submits a request to join a private Office 365 group. Office 365 sends an Actionable Message to the person who owns the group to approve or decline the request. The card included in the message contains all the information the approver might need to quickly understand who submitted the request and any message they included to explain their request. It also includes Approve and Decline actions that can be taken right from Outlook. The owner approves the request, and the card updates to indicate the outcome.

The new member of the group submits a second request to add her team members to the group. Office 365 sends an Actionable Message to the owner with clear information about who submitted the request and the new members to add. The recipient can approve all, some, or none of the proposed new members. The owner approves one new member, and the card updates to indicate the outcome. The approved member is no longer selectable, while the remaining member remains selectable.

The owner declines the other requested new member, and the card updates to indicate the outcome. Both members are no longer selectable, and the action buttons are removed.

Actionable messages via Office connectors: task management scenario

Adele Vance and her team use Trello as their task management system. Adele has configured the Trello connector in her account, and will receive granular notifications as activity occurs in the Trello boards she is interested in.

Shiva, in Adele's team, creates a new Trello card in the "Hiring" board. He needs the latest job postings to be published. Adele receives an actionable message that tells her all about the new card and the task it represents: who created it, in which list, what the due date is, and more.

Adele has a few notes she recently took on a piece of paper with important things that should be mentioned in the job postings. She decides to add these as a comment to the Trello card. She clicks the Add a comment action, and is presented with a text input field in which she can type her notes:

Adele then clicks the Save button, and the notes are immediately saved to the Trello card. A confirmation appears at the bottom of the message:

Office connectors

Office connectors are a great way to get useful information and content into your Office 365 Groups in Outlook or Microsoft Teams. Any user can connect their group or team to services like Trello, Bing News, Twitter, etc., and get notified of activity from that service. From tracking a team's progress in Trello, to following important hashtags in Twitter, Office connectors make it easier for an Office 365 group in Outlook, Microsoft Teams, or Yammer to stay in sync and get more done.

Accessing Office connectors from Outlook

Office connectors are available for both the inbox and Groups for any Office 365 Mail user. Connectors can be managed in either Outlook on the web, or Outlook 2016 or later on Windows.

Accessing connectors in Outlook on the web

Inbox connectors

Accessing connectors in Outlook 2016 on Windows

Users access both inbox and group connectors from the Store button. The Store button loads connectors for the inbox if Outlook is currently displaying a mail folder in the user's mailbox, and loads connectors for the currently selected group if displaying a group.

In the inbox case, the Store dialog displays the Add-ins tab by default. Connectors are available in the Connectors tab.

Release Notes

Currently, you can only configure connectors from Outlook on the web, or Outlook 2016 or later on Windows, but you can view information posted by Connectors to your Group or inbox in multiple clients such as Outlook on the web, Outlook 2016 or later, and the Office365 Groups Mobile app.
