Facebook wants anyone around the world to be able to message you on Facebook, but to do it, the social network is killing a part of your Facebook inbox you probably never knew you had. Facebook’s barely known and rarely used ”Other” inbox will soon be discontinued in favor of a new addition to Messenger called Message Requests.
If you don’t know what the Other inbox is, login to facebook.com/messages and at the top of the left-hand navigation panel you’ll see the “Other” heading. In there are messages from non-Facebook friends and Facebook pages. The idea behind “Other” was to deliver unauthorized messages—i.e. messages from non-friends—without overloading your inbox.
