如何读未读电子邮件在ASP.NET中使用Exchange Web服务:我使用的Exchange Server 2007 SP3

我能够连接Exchange Web服务，使用下面的代码

    ExchangeServiceBinding esb = new ExchangeServiceBinding();

    esb.RequestServerVersionValue = new RequestServerVersion();

    esb.RequestServerVersionValue.Version = ExchangeVersionType.Exchange2007_SP1;

    esb.Credentials = new NetworkCredential("<user_id>", "<password>", "<domain>");

    esb.Url = @"https://<server_fqdn>/ews/Exchange.asmx";</server_fqdn></domain></password></user_id>

我期待的代码只读未读邮件。

可以请你帮我吗？| Pradip_Bobhate
