So, you have probably had times when you wanted to acknowledge you received an email message, but you did not really have anything to say in reply. You reply “Thank you.” The other user has to spend time reading another email. Rarely they might even reply “You’re welcome.” You have to read another email. Who is to say it stops there? Maybe soon you are exchanging photos of your pets, or speculating on whether Aaron Rodgers is past his prime.
With Outlook you can acknowledge an email without sending a reply.
Simply click the like button. You can find this just to the left of the the reply button on the web client.

The person who sent the mail will get an alert indicted by a number by the bell at the top of the screen. You are both back to doing what you were doing before.

Feel free to share your favorite tip about Outlook, share a pet photo, or share your opinion on Green Bay quarterbacks- past, or present in the comments.
