That doesn't make sense
No, you can't. Once a message is sent, it can't be unsent.
If you send someone a message on Facebook Messenger and then block them, you will not be able to see whether they have read your message. Once you block someone, you lose access to any interactions with them, including read receipts for messages. Additionally, the message may not even appear in their inbox once you block them.
It's possible to lose a message in Facebook in the middle of typing it if you accidentally hit another key on your keyboard. Also, occasionally, Facebook will just drop a private message in the middle of typing. Once gone, it's gone forever, there is no recovery.
Facebook does not store deleted chat history. Once a message or conversation is deleted by a user, it is permanently removed and cannot be retrieved by Facebook or anyone else.
This helps to get a message to people quicker. The message would come in all at once and not be broken up.
No
unfortunately, you cant. Once people have it, they cant get rid of it again!
Unfortunately, once notification is deleted on Facebook, it is gone forever. The only exception to this is if the user has archived the information, rather than deleting it. In that case, it would still be accessible under the message tab.
Despite various rumors, there is no way of retrieving deleted messages on Facebook. Immediately after you delete a message in your private Inbox, you are given the option to "Undo" - above the message - but that is it. Once a message is gone, it's gone; there is no way to recover it later.

First, you go to the Facebook Website, http://www.Facebook.com and then once you successfully logged into your account, then can you begin searching for people's Facebook account. Once you've logged in, you simply go onto the Facebook Search Bar on the top of the screen, and type the persons name you want to look up.
