People who want to connect with old friends and classmates need only send a message on the social media platform to reconnect, strike up a conversation and plan meetups.

But what if you're sending messages that are never seen? And what if people are sending you messages that you've never seen?

A Facebook messaging feature holds messages from Facebook users who you are not Facebook friends with in a separate folder.

To see the hidden messages, you must access message requests in your account.

Here's how to do it:

Facebook (online): Click on the messages icon at the top of the screen in the blue bar > Message Requests > See filtered requests

Messenger app (mobile): Settings > People > Message Requests > See filtered requests

Have fun perusing old messages, and hopefully, it's not too late to respond to some of them!
