Issues: NETWORKNET-33125 (Fixed)

exchange: 401: Unauthorized

I can't seem to connect with EWS and Office365. This used to work. I know the credentials and the URLs are good because I can authenticate and see services.wsdl in a browser for both BPOS and Office365.Using Microsoft.Exchange.Webservices library works fine for both URLs

The BPOS url+credentials work fine, but the Office365+credentials (which are valid) do not. The following exception occurs whenever I try to use the auto discovered Office365 URL, and it occurs on the line requesting the inbox uri (basically the first web operation):
The request failed with HTTP status 401: Unauthorized.

using Aspose.Email.Exchange;
using Aspose.Email.Mail;

namespace testauth2
{
    class Program
    {
        static void Main(string[] args)
        {
            x x = new x();
            x.y();
        }
        class x
        {
            ExchangeWebServiceClient client_aspose;
            public void y()
            {
                string url_bpos = "https://red001.mail.microsoftonline.com/ews/exchange.asmx";
                string url_o365 = "https://********.outlook.com/EWS/Exchange.asmx";//obtained using auto discover
                client_aspose = new ExchangeWebServiceClient(url_o365, "********@*********.***", "*********");
                string inboxUri = client_aspose.MailboxInfo.InboxUri;
                ExchangeMessageInfoCollection items = client_aspose.ListMessages(inboxUri, 100);
                MailMessage mm = client_aspose.FetchMessage(items[0].UniqueUri);
            }
        }
    }
}

Re: exchange: 401: Unauthorized

Hi,

Thank you for providing us the test account details.

I can connect to Outlook365 using Aspose.Email for .NET v1.3.0. Please check the below source code for your reference.

string mailboxURI = "https://********.outlook.com/EWS/Exchange.asmx"; var username = "****@*****.com"; var password = "*****"; var domain = ""; NetworkCredential credential = new NetworkCredential(username, password, domain); ExchangeWebServiceClient client = new ExchangeWebServiceClient(mailboxURI, credential);

ExchangeMessageInfoCollection items = client.ListMessages("Inbox", 10);

Please give it a try at your end and let us know of your feedback.

Re: exchange: 401: Unauthorized

using 1.3.0 net3.5

Length cannot be less than zero.
Parameter name: length

happens when trying to use the line

ExchangeMessageInfoCollection items = client_aspose.ListMessages("Inbox", 100);

edit: I copied your code exactly and am still getting that exception when at the line:

ExchangeMessageInfoCollection items = client.ListMessages("Inbox", 10);

Re: exchange: 401: Unauthorized

I'm afraid that while using the 1.4.0.0 release, the exception still happens when trying to use the function ListMessages.

ArgumentOutOfRangeException
Length cannot be less than zero.
Parameter name: length

string mailboxURI = "https://****************************************";
var username = "******@********.com";
var password = "********";
var domain = "";
NetworkCredential credential = new NetworkCredential(username, password, domain);
ExchangeWebServiceClient client = new ExchangeWebServiceClient(mailboxURI, credential);
ExchangeMessageInfoCollection items = client.ListMessages("Inbox", 10);

Do you still have the test credentials and url that we prepared for you to debug with?

P.S. The Error 401 unauthorized no longer happens, so that IS fixed, but the exception when listmessages remains.

P.P.S. When using the correct method of ListMessages it works (retrieve inbox uri) when using your suggested method of just using "inbox" the exception happens. So actually the confusion is due to you telling me to use your broken example because the unbroken working way to do it is:

string inboxUri = client_aspose.MailboxInfo.InboxUri;
ExchangeMessageInfoCollection items = client_aspose.ListMessages(inboxUri, 100);

and the bad way to do it is:

ExchangeMessageInfoCollection items = client.ListMessages("Inbox", 10);

so after all the bugs are all fixed.

Re: exchange: 401: Unauthorized

Hi Matthew,

Thank you for your feedback and apologies for your inconvenience.

According to my knowledge both below mentioned source code lines should produce the same result. For a confirmation, I have logged your comments to the ticket already associated with this thread.

var messages = client.ListMessages(client.GetMailboxInfo().InboxUri);
var messages = client.ListMessages("Inbox");

Also, I am getting the ArgumentOutOfRangeException on the second source code line, so I am waiting for a feedback from the development end on this.
