指定日期时WebDAV Exchange 2003失败

我正在使用以下代码从Exchange 2003服务器检索电子邮件。所有人都在星期五工作，现在失败了。指定日期时WebDAV Exchange 2003失败

从一些调查我已经缩小到targetDate变量。似乎4月份的日期是否会从服务器返回400。我已经评论了这一行，并尝试了2012年3月29日，2012年4月1日，2012年4月10日（今天）的各种日期，4月份的日期似乎失败了。

某种生病的愚人笑话？

代码本身是从这篇文章中得出：http://www.codeproject.com/Articles/42458/Using-Exchange-2003-with-Webdav-Send-Retrieve-Atta

终于得到它的工作。确切targetDate投包括T00：00：..ž部分必须http://msdn.microsoft.com/en-us/library/aa123600%28v=exchg.65%29.aspx

符合规格要求我现在有：

DateTime targetDateTime = DateTime.Today; 
string targetDate = targetDateTime.ToString("yyyy-MM-dd");

剪断

+ "AND \"urn:schemas:httpmail:datereceived\" >= CAST(\"" + targetDate + "T00:00:00Z" + "\" AS 'dateTime.tz')"

注意，秒部分两个零而不是三个。
