As is the case with WhatsApp, time limits will be involved, meaning you won't be able to remove any of the things you said in past chats.
While Facebook-owned WhatsApp gives you an hour to delete sent messages, Messenger isn't going to be so magnanimous. At least, that's how its worked for users whose name isn't Mark Zuckerberg. It'll only let you unsend messages for up to 10 minutes after you first send them.
Yet users will need to be quick as Facebook are giving those wanting to retrieve their messages just 10 minutes to do so.More news: Thugs of Hindostan fails to beat Baahubali

Users of the popular messaging site and app will be given the opportunity to delete a message after it has been sent.
Google's for Gmail allows users to choose how long they have to unsend an email.
Bottom line: Great news for people who take their phones with them on nights out: Facebook Messenger's long-talked-about unsend feature is nearly here. This gives the recipient the opportunity to read the messages, even if you decide to take it back within the timeframe its eligible to be "unsent".
