Explore Microsoft Outlooks new reactions feature to easily respond to emails, enhancing productivity and communication within Exchange Online mailboxes.

The new reactions feature in Outlook allows users to send a quick reaction to an email without having to create an entire email reply. The reactions work in Exchange Online mailboxes and, by default, only when the person you're messaging with is also in your organization and using an Exchange Online mailbox.
To react to an email, you select the reactions button near the top right of the message window, which will display a gallery of reactions to choose from. Once you select your reaction, it will be sent to the message sender and displayed for anyone else in the conversation. If you want to change your reaction, you simply select a different reaction and your initial reaction will be replaced by the new one.
When someone reacts to a message, their reaction will be displayed below the message controls towards the top right corner of the message window. You can also see reactions to messages you sent in the notifications feed of Outlook. If you've received any reactions in the previous day or so, you'll get a digest email that summarizes the reactions you've received. You can choose to unsubscribe from the digest email if you'd prefer not to receive it.
The reactions feature was rolled out to all platforms (Windows, Mac, iOS, Android, and Web) as of December 2022. However, if you're on the Monthly Enterprise, or one of the Semi-Annual channels, you might not see the feature on Windows quite yet. Furthermore, if your Microsoft 365 tenant is a GCC (Government), DoD, or Gallatin (China) environment, you might not have this feature quite yet. This feature is not currently supported with senders that are outside of your organization. To use reactions in a Microsoft Exchange shared mailbox, you must open the shared mailbox in Outlook on the web.
For administrators, the Outlook team is currently working to add Microsoft 365 tenant admin controls. It's important to note that reactions cannot be disabled per user, and only individual users can unsubscribe from the digest email. If an administrator needs to disable reactions, they can open a ticket to be placed on a temporary disallow list.
