无法设置收件人-O365

Question

我正在尝试使用O365

发送电子邮件

但是，如果不访问私有属性，我找不到设置收件人的方法。

from O365 import *

my_protocol = MSGraphProtocol(api_version='beta')
account = Account(
    credentials=('id', 'id'),
    protocol=my_protocol
)
if not account.is_authenticated:  # will check if there is a token and has not expired
    # ask for a login
    account.authenticate(scopes=['mailbox', 'message_send'])

msg = Message(parent=account)
msg.body = 'Hi, foobar.'
msg.subject = 'Bar Foo'

msg.to = Recipient(address='foobar@outlook.com', name='lucas') # dont work
msg._Message__to._recipients = [Recipient(address='foobar@outlook.com', name='lucas')] # works but very bad way i supossed
msg.setRecipients(Recipient(address='foobar@outlook.com', name='lucas')) # some old tutorials used this, but dont work either

msg.send()

这肯定是一个非常愚蠢的问题，但是我从文档中读取了类，却找不到收件人的设置器。

谢谢！
