You can send reactions to emails that you receive in your Outlook inbox. In the coming months, it will not be applicable to all emails you receive, as senders can control who gets to send reactions.
Microsoft introduced the ability to react to Outlook emails last year but it now wants to make the necessary adjustment to it to give senders more control over reactions functionality. Microsoft is currently working on a new feature for Outlook that will let the senders decide if they want receivers to react to certain emails.
Microsoft’s «suite of improvements» for Outlook includes giving the senders the option to disallow senders from reacting to emails.
