python - exchangelib - 自动发现协议(protocol)中的所有步骤均失败

Question

我在 python 中使用 exchangelib 时遇到问题。我试试这个示例代码:

from exchangelib import DELEGATE, Account, Credentials

creds = Credentials(
    username='xxxx\\username', 
    password="mypassword"
)

account = Account(
    primary_smtp_address='surname.name@xxxx.fr',
    credentials=creds, 
    autodiscover=True, 
    access_type=DELEGATE
)

# Print first 10 inbox messages in reverse order
for item in account.inbox.all().order_by('-datetime_received')[:10]:
    print(item.subject, item.body, item.attachments)

我尝试了不同的用户名，但没有任何效果，而且我总是收到相同的错误消息:

AutoDiscoverFailed: All steps in the autodiscover protocol failed

顺便说一句，为了以防万一，我尝试使用为 C# 编码的 Exchange Web 服务，并且它与此信誉完美配合，我可以发送邮件:

static void Main(string[] args)
{
    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
    // The last parameter is the domain name
    service.Credentials = new WebCredentials("username", "password", "xxxx.lan");
    service.AutodiscoverUrl("surname.name@xxxx.fr", RedirectionUrlValidationCallback);
    EmailMessage email = new EmailMessage(service);
    email.ToRecipients.Add("surname.name@xxxx.fr");
    email.Subject = "salut ";
    email.Body = new MessageBody("corps du message");
    email.Send();
}

private static bool RedirectionUrlValidationCallback(string redirectionUrl)
{
    // The default for the validation callback is to reject the URL.
    bool result = false;

    Uri redirectionUri = new Uri(redirectionUrl);

    /* Validate the contents of the redirection URL. In this simple validation
       callback, the redirection URL is considered valid if it is using HTTPS
       to encrypt the authentication credentials. */
    if (redirectionUri.Scheme == "https")
    {
        result = true;
    }
    return result;
}

提前致谢!

Answer 1

我终于通过这个配置成功了:

from exchangelib import DELEGATE, Account, Credentials, Configuration

creds = Credentials(
    username="domain_name\\username", 
    password="password"
)

config = Configuration(server='mail.solutec.fr', credentials=creds)

account = Account(
    primary_smtp_address="my email address",
    autodiscover=False, 
    config=config,
    access_type=DELEGATE
)

对于那些会遇到同样问题的人，您可以通过右键单击“计算机”和“属性”来找到您的域名。例如，用户名和密码是您用来连接公司邮箱的用户名和密码。对于配置中的服务器，对我来说，这个有效:“mail.solutec.fr”，其中 solutec 是我公司的名称，fr 是法国的名称。

看来这个自动发现的家伙真的不喜欢我^^

无论如何感谢您的帮助，祝您有美好的一天!
