How to get all messages expanded in conversation mode in Outlook 2013?

When selecting Show as conversation view mode in Outlook 2013

There are 3 display modes as below snapshots i.e.

1. Collapsed mode

2. Expanded mode #1 - my response mails (i.e. the ones in Sent box) not displayed

3. Expanded mode #2 - my response mails are displayed

I just want mode #2 to be the only one to display my messages. How can I do that?

Just check Always Expand Selected Conversation in Conversation Settings menu

(right below Show as Conversations check).

After checking Always Expand Selected Conversation in the Conversation Settings menu, click the Change View menu item and choose Apply Current View to Other Mail Folders... to apply the Conversation Settings to all folders.
