Having a problem finding replies to your email?

The In Box layout has changed a bit. See snippet below: Note the arrow pointing to the left is an indication that we replied to the email received. 

See the box with the caret (arrow) pointing to the right? It's an indication that we received a response. 

To read the response, click on the caret, then click on the response in the drop down menu to read the reply.
Note: caret is pointing down to the new message and the arrow to pointing to the right is an indication that we responded to the message.
