各位大佬好，我遇到个棘手的问题，想请大家帮忙看看：

我写了一段Python代码，功能是轮询Outlook主收件箱里的双因素认证邮件，提取里面的6位验证码，自动填入网页并提交。现在我想在完成这些操作后把这封认证邮件删掉，但试了好几种写法都没成功，实在找不到问题出在哪了。

另外提一句，我原本还打算修改这段代码——现在的判断条件是len(messages)==1，我想改成直接取最新的那封邮件来处理，但不管逻辑怎么改，删除邮件这个需求是一定要实现的。

下面是我的代码片段（部分敏感信息已留空）：

# Part 2: Retrieve passcode from email for authentication
import win32com.client
import datetime
from datetime import timedelta
import time
import re
from selenium.webdriver.common.by import By

outlook = win32com.client.Dispatch('outlook.application')
mapi = outlook.GetNamespace("MAPI")
inbox = mapi.GetDefaultFolder(6)

received_dt = datetime.datetime.now() - timedelta(minutes=5)
received_dt = received_dt.strftime('%m/%d/%Y %H:%M %p')

delay = 15  # seconds
waitloop = 1
passcodefound = 0

# 原代码这里写的是passcodefound ==1，应该是笔误，否则循环根本不会执行
while passcodefound == 0:  
    messages = inbox.Items
    messages = messages.Restrict("[ReceivedTime] >= '" + received_dt + "'")
    messages = messages.Restrict("[SenderEmailAddress] = '  '")
    messages = messages.Restrict("[Subject] = ' '")
    print(f"filtered inbox, {str(len(messages))} found.")

    if len(messages) == 1:
        for message in messages:
            text = message.Body
            CodeRegexVariable = re.compile(r'(\d\d\d\d\d\d)')
            code = CodeRegexVariable.search(str(text))
            answer = code.group()
            print(answer)
            print("2 Factor Authentication email found and processed.")
            
            # 填充验证码并提交
            passcode_field = driver.find_element(By.ID," ")
            passcode_field.clear()
            passcode_field.send_keys(answer)  # 原代码这里是空的，推测应该传入提取到的验证码
            submit_button = driver.find_element(By.ID,"otpSubmitButton")
            submit_button.click()
            
            # 尝试删除邮件
            message.Delete()
            passcodefound = 1
            break
    else:
        waitloop += 1
        total_wait_time = waitloop * delay
        print(f"Authentication email not found. Wait time total = {str(total_wait_time)} seconds. Waiting for {str(delay)} seconds and trying again")
        time.sleep(delay)

我已经尝试过这些调整，但都没解决问题：

• 把message.Delete()移到print("2 Factor Authentication email found and processed.")后面，结果还是删不掉邮件；
• 取消message.Delete()和break的缩进，结果直接报错“break outside loop”；
• 只取消message.Delete()的缩进并注释掉break，虽然没报错，但邮件依然没被删除。

有没有大佬能帮我看看哪里出问题了？或者有没有更可靠的删除Outlook邮件的方法？
