我正在尝试使用EWS访问收件箱邮件。 Kerberos已配置。但是当我在我的webpart中使用service.UseDefaultCredentials = true时,我得到401错误(未经授权)。什么是解决此问题的解决方案。
private static bool ValidateCertificate(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors policyErrors) {
return true;
}
protected void Page_Load(object sender, EventArgs e)
{
try
{
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(ValidateCertificate);
service.UseDefaultCredentials = true;
service.Url = new Uri(EWSuri.uri);
SearchFilter sf = new SearchFilter.SearchFilterCollection(LogicalOperator.And,
new SearchFilter.IsEqualTo(
EmailMessageSchema.IsRead, false), new SearchFilter.IsGreaterThan(ItemSchema.DateTimeReceived, DateTime.Now.AddDays(-14)));
FindItemsResults<Item> findResults = service.FindItems(
WellKnownFolderName.Inbox, sf,
new ItemView(int.MaxValue));
emailblock.InnerHtml = "<div data-itemscount=\"" + findResults.Items.Count + "\"></div>";
foreach (Item item in findResults.Items)
{
EmailMessage mes = (EmailMessage)item;
emailblock.InnerHtml += "<div class=\"emailitem\"><p class=\"emailline clearfix\"><span class=\"emailfield\">From:</span>" +
"<span class=\"emailtext\">" + " " + mes.Sender.Name + "</span></p>" +
"<p class=\"emailline clearfix\"><span class=\"emailfield\">Subject:</span>" +
"<span class=\"emailtext\">" + " " + item.Subject + "</span></p>" +
"<p class=\"emailline clearfix\"><span class=\"emailfield\">Received:</span>" +
"<span class=\"emailtext\">" + " " + item.DateTimeSent + "</span></p></div>";
}
}
catch (Microsoft.Exchange.WebServices.Autodiscover.AutodiscoverRemoteException ex)
{
Console.WriteLine("Exception thrown:{0}" ,ex.Message);
}
}

尝试提供其他具有权限的登录信息或凭证。如果您在AD环境中,请不要忘记指定域名:
exchangeService = new ExchangeService(ExchangeVersion.Exchange2010_SP1);
exchangeService.Credentials = new NetworkCredential(ExchangeConfig.user,
ExchangeConfig.password,
ExchangeConfig.domain);
exchangeService.AutodiscoverUrl(ExchangeConfig.usermail);

service.UseDefaultCredentials = true;当您使用模拟使用自己的计算机登录时,这将无效。要解决此问题,您需要获得对所有邮件帐户具有读取权限的管理员用户,然后传递admin用户的显式凭据,然后使用EWS的模拟类,并解决问题
