這是我嘗試解決的情況：我可以使用用戶myuser訪問服務郵箱serviceMail。所以這不是我的個人郵箱，而是我公司的另一個郵箱設置，我們收到了用於各種目的的電子郵件。我知道我有權訪問它，因爲我在Outlook中添加了這個郵箱，並且能夠像通常一樣爲我自己的電子郵件檢查收件箱。我正嘗試使用EWS編寫一個c＃程序，該程序將從'serviceMail'收件箱中的電子郵件中獲取附件。嘗試查找項目時，我正在獲得「401 Unauthroized Access」。我究竟做錯了什麼？我的代碼如下。401使用EWS連接郵箱時未經授權訪問
這裏是我如何連接到服務：
public ExchangeService ConnectToExchangeServer()
{
const string strMailbox = "[email protected]";
const string strLoginUser = "[email protected]";
const string strLogingUserpwd = "pwd";
const string strO365Url = "https://outlook.office365.com/EWS/Exchange.asmx";
try
{
exchange = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
exchange.Credentials = new WebCredentials(strLoginUser, strLogingUserpwd, "sabra.com");
// exchange.AutodiscoverUrl(strMailbox,RedirectionUrlValidationCallback);
exchange.Url = new Uri(strO365Url);
return exchange;
}
catch (Exception ex)
{
}
return exchange;
}
下面是試圖找到項目
ExchangeService service = ga.ConnectToExchangeServer();
TimeSpan ts = new TimeSpan(0, -1, 0, 0);
DateTime date = DateTime.Now.Add(ts);
SearchFilter.IsGreaterThanOrEqualTo filter = new SearchFilter.IsGreaterThanOrEqualTo(ItemSchema.DateTimeReceived, date);
if (service != null)
{
//FindItemsResults<Item> findResults = ga.exchange.FindItems(WellKnownFolderName.Inbox, filter, new ItemView(50));
//FindItemsResults<Item> findResults = ga.exchange.FindItems(WellKnownFolderName.Inbox,);
// Return a single item.
ItemView view = new ItemView(1);
string querystring = "HasAttachments:true Subject:'Message with Attachments' Kind:email";
// Find the first email message in the Inbox that has attachments. This results in a FindItem operation call to EWS.
FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Inbox, querystring, view);
foreach (Item item in findResults)
{
EmailMessage message = EmailMessage.Bind(ga.exchange, item.Id);
if (message.HasAttachments && message.Attachments[0] is FileAttachment)
{
FileAttachment fileAttachment = message.Attachments[0] as FileAttachment;
//Change the below Path
fileAttachment.Load(@"D:\\QlikData\\Lean\\EmailExtract" + fileAttachment.Name);
// lblAttach.Text = "Attachment Downloaded : " + fileAttachment.Name;
}
else
{
// MessageBox.Show("No Attachments found!!");
}
}
if (findResults.Items.Count <= 0)
{
//lstMsg.Items.Add("No Messages found!!");
}
}
我得到錯誤「的請求失敗代碼遠程服務器返回錯誤：（401）未經授權。「 FindItemsResults findResults = service.FindItems（WellKnownFolderName.Inbox，querystring，view）代碼行。
任何想法？
