We accidentally deleted a message or chat from Facebook Messenger and we no longer know how to recover it "> Facebook Messenger page, press the gear icon (just above the chats at the top left) and select the Chat Archived item. 
From here we can scroll through all the archived conversations and search for the one that interests us; once found, we will be able to access the entire conversation and recover the messages. In order to unlock the chat and return it to view, just write on it (it will be available again and will no longer be archived).
To check the chats stored by the Facebook Messenger app for Android and iOS, all we have to do is open the app, tap on the search bar at the top and type the name of the contact from which we want to recover the deleted chat; a list will open with the contacts with whom we have established a connection, just press on the right chat and scroll until you find all the deleted messages.
Download a copy of Facebook Messenger messages
Another method that we can use to recover Facebook Messenger messages involves downloading the personal data archive, so that we can personally check everything we have done on our Facebook profile.First we access our Facebook profile from the website, press the down arrow (present at the top right, next to the symbol of?), Select the Settings item and open the Your information on Facebook menu.
In the screen that will open, press on the View item next to the Download your information section and, in the next window, press on Deselect all ; now scroll down the page until you find the Messages section, make sure to put the check mark, go back to the top of the page, check that all my data, HTML and Media are set as entries in the upper fields then click on Create file .
The creation of the personal file will start and, at the end, the download of the HTML file will start directly from the chosen browser.
At the end of the download we will have to do is open the HTML file with any web browser, so as to view all the messages and chats exchanged on Messenger since we created the profile (including messages deleted, deleted or archived by mistake).
If we are unable to open the HTML file from the browser, we recommend downloading the Notepad ++ program, available for free for Windows.
To download a copy of the messages from your smartphone or tablet, simply open the Facebook app, available for Android and iOS, press on the menu with the three horizontal lines at the top right, scroll and open the Settings and privacy section then press on the menu Settings . In the new screen we press on the menu Download your information, we press again on Deselect all, we make sure that there is a check mark on the item Messages, we scroll down, we make sure that all my data, HTML and Media in the fields are selected then we press finally on Create the file .
The same HTML file seen from the PC will be downloaded to the mobile device; to open it we will have to use any web browser or a dedicated app such as HTML Reader / Viewer (for Android) and HTML Viewer Q (for iOS / iPadOS).
Look in the Android cache
If we have deleted a chat or message from the Messenger app for Android, we can check the cache of the app, where you can find (with a little luck) the newly deleted chat.To carry out this check we install the Solid Explorer app on our Android smartphone or tablet, press on Internal memory in the interface then go to the following path Android -> data -> com.facebook.orca -> cache .
If the chat has been canceled recently, we will find it here, ready to be viewed (as HTML). If, on the other hand, we don't find anything, there is no way to recover the chat or messages if you don't contact Facebook directly.
Contact Facebook
If all our efforts have not gone into recovering Facebook Messenger messages, you just have to contact Facebook support.
We carry out a search inside the upper bar specifying the problem and, in case we are asked to contact by email, we explain about it the whole problem (from the accidental cancellation of the chat up to the recovery attempts already made).
If we do not receive a reply shortly, we try again with an email in English (perhaps helping with our guide to Programs to write in English with correct spelling and grammar ).
Conclusions
Here above we have shown you all the safe and valid methods to recover Facebook Messenger messages deleted by mistake or by distraction.If we have not found the message that we were looking for and that we have eliminated, then there is really no hope of being able to recover it easily.
