Question

我的公司刚刚将一些邮箱移至O365。不幸的是，这破坏了使用EWS创建的应用程序。尝试调出AutodiscoverUrl（）时，遇到错误。

“找不到自动发现服务。”

代码：

        service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
        service.UseDefaultCredentials = true;
        service.AutodiscoverUrl(mailbox, RedirectionCallback);

        private bool RedirectionCallback(string url)
        {
            return true; 
        }

我也尝试将URL设置为以下

service.Url = new Uri("https://autodiscover.MYDOMAIN.com/autodiscover/autodiscover.xml");
service.Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx");

这些都没有解决问题。有人知道从这里去哪里吗？

Answer 1

service.UseDefaultCredentials应该为false，因为您需要使用电子邮件+密码（作为安全字符串）进行连接
使用最新的ExchangeVersion值

URL为https://outlook.office365.com/EWS/Exchange.asmx

public ExchangeService Connect()
{
    var lastExchangeVersion = Enum.GetValues(typeof(ExchangeVersion)).Cast<ExchangeVersion>().ToList().Last();
    var service = new ExchangeService(lastExchangeVersion)
    {
        Url = new Uri("https://outlook.office365.com/EWS/Exchange.asmx"),
        Credentials = new NetworkCredential(_cloudEmail, _cloudPassword)
    };
    return service;
}
public SecureString ConvertStringToSecure(string password)
{
    if (string.IsNullOrWhiteSpace(password)) return null;
    var result = new SecureString();
    foreach (char c in password) result.AppendChar(c);
    return result;
}

升级到O365破坏了EWS自动发现
