لا يمكن لـ C# قراءة رسائل البريد الإلكتروني باستخدام webdav وfba

Question

ملخص:

أواجه مشكلة في الاتصال بـ exchange 2007 mailbox الذي يقوم بتشغيل FBA باستخدام كود C# الخاص بي باستخدام webdav.

تفاصيل:

يجب أن يعمل هذا الرمز أدناه مع خادم Exchange 2007، وأن يتصل ويقرأ البريد الإلكتروني من صندوق بريد.

لقد قمت بتجربة EWS ولكن لم يكن هناك أي معنى ولم أتمكن من تشغيله.

أدناه هو الكود الخاص بي.أنا أستخدم عنوان url الخاص بـ outlook للحصول على ملفات تعريف الارتباط التي أحتاجها لتسجيل الدخول عبر webdav إلى عنوان url الخاص بالتبادل.

خطأ:

440 login timeout on the request.

المنطقة التي ينكسر فيها الكود الخاص بي:

Response = (HttpWebResponse)Request.GetResponse();

لماذا يتم تفويت ملف تعريف ارتباط واحد؟

Answer 2

يصدر الخادم أ HTTP/1.1 440 مهلة تسجيل الدخول، عندما يتم تمكين FBA ويكون هناك طلب HTTP أو طلب WebDav تم إجراؤه مقابل التبادل 2003/2007..إليك بعض عينة من الرموز وهنا التفاصيل حول FBA
