If you’re on a Windows, Mac, Linux, or Chromebook computer, use the official Facebook website to get access to all your archived messages.

• Start by launching a web browser on your computer and opening Facebook. Sign in to your account on the site if you haven’t already.
• After signing in, in Facebook’s top-right corner, click the “Messenger” icon.

At the bottom of your message list, click “See All in Messenger.”

Next to the “Chats” header at the top, click the three dots.

In the three-dots menu, select “Archived Chats.”

On the left pane, in “Archived Chats,” you will find all your archived messages. You can open the full view of a conversation by selecting a chat in the sidebar.

If you want to view your archived chats from your iPhone, iPad, or Android phone, use Facebook’s Messenger app. Start by launching Facebook Messenger on your phone. In the app’s top-left corner, tap your profile icon.

On the “Me” page, scroll down and tap “Archived Chats.”

You’ll see an “Archived Chats” page listing all your archived conversations. Tap a chat to open it.
