Working of End to end encryption

My friend had uninstalled the whatsapp and since i didn't know this i had sent him a message which hasn't delivered yet. Today it showed the end to end encryption message. Has he installed the latest version? If yes then why my message hasn't delivered yet? His last seen is still one month old. Why did this end to end encryption message came today only and that too when he hasn't opened the whatsapp?

    The encryption message is standard in your app. This has nothing to do with opening whatsapp on your friend’s side.
