How do I get the folder name to speak and display in message box?

By default the folder name does not display in the message box. 

However you can edit the folder to make this work.

1. Navigate to one level above the folder. 
   
2. Tap the Edit button to enter the edit mode.
   
3. Tap the folder to select it. 
   
4. Now tap the Change button on the top right corner. This opens the Edit window for the folder.
   
5. Now turn ON the 'Show in Message box' option (to the right of Captions field).
   
6. Tap Done to save the changes. Now when you tap the folder, the folder name is displayed in the message box.
