Conversations allow you to reduce clutter in your inbox and follow email chains by grouping similarly-titled emails together. To enable this view in Microsoft Outlook 2013, follow these steps:

1. Click the “View” tab at the top of your Outlook home screen.
2. Check the box that says “Show as Conversations”. To turn it off instead, uncheck the box.
3. Select the folder you want to apply “Conversations view”. Click on “this folder” button.
4. If you’ve just turned the feature on, you’ll notice little arrows next to emails that have been threaded. It’s pretty easy to reset outlook settings . Clicking on the arrow reveals all the messages that have been grouped together under that thread.
5. You can further customize the “Conversations” view. Click on “Conversation Settings” and select any option as per your requirement.
