Python 3 - How to extract message from an email [pending]

I have this code to extract messages from an email, but the output shows the message and some encrypted information. I need help getting the message.

In another version of the code, I tried the imaplib library but I was unsuccessful because all the messages were encrypted so I now used poplib .

Then I want to get the Subject of the email, the date and who sent it.

#!/usr/bin/env python3
# -- coding: utf-8 --

import email
import poplib

login = input('Email: ')
password = input('Password: ')
pop_server = 'pop-mail.outlook.com'
pop_port = 995

mail_box = poplib.POP3_SSL(pop_server, pop_port)
mail_box.user(login)
mailbox.pass_(password)
numMessages = len(mail_box.list()[1])

if numMessages > 15:
    numMessages = 15
for i in range(15):
    (server_msg, body, octets) = mail_box.retr(i+1)
    for j in body:
        try:
            msg = email.message_from_string(j.decode("utf-8"))
            strtext = msg.get_payload()
            print(strtext)
        except:
            pass

Update with Output:
