Why emails disappear once after reply

This is my first experience on Microsoft Outlook 2013 and I was curious on what’s go wrong on my mailbox (Inbox) as why my email always disappeared after I reply to an particular email.

After do a search…. just realized that a new update on Outlook so called “View” profile slightly change from previous Outlook version.

Here is my “View” profile that I’ve made (from default View profile)

- Sort with Received (descending)
- Show as Conversation
- Conversation settings > uncheck Show message from other folders

I’m happy with my Outlook message “View” now :)
