Sharepont2010 如何单点登录 OWA

Question

有一个webpart显示 owa中未读邮件《 目前需要点击 某条未读邮件 ，直接向owa中打开一样，定位到该邮件!

目前问题:

1.点击邮件时，连接到owa需要用户输入用户名和密码登录， sharepoint和owa都是基于AD，想的是，sharepoint已经验证 了，owa就不输入密码了.

目前使用的是记住密码的。

2.https://mail.server.com/owa/?ae=Item&a=Open&t=IPM.Note&id=RgAAAABh3SkfFRJjTZvjszfyM4LlBwB4XADDrEFhSI1I0ylHUJ6jAAAAeFnRAAB4XADDrEFhSI1I0ylHUJ6jAAAHaZQWAAAA

该ID不知道如何生成? 关于这个问题另参考 :http://social.technet.microsoft.com/Forums/zh-CN/exchangesvrdevelopment/thread/17cdb574-cd96-49c4-9f7b-0e012842954f

i create a post in the notes folder of a specified mailbox. I use the EWS 2007 to do this. Then I would like to return the URL to open this post in a web-browser. However, it should open the view in which I can write an reply. The URL looks in general thus:

https://SERVER_ADRESS/owa/?ae=PreFormAction&a=PostReply&t=IPM.Post&id=RgAAAADMJNzMj%2brsS4PO%2fGghaEMzBwC%2bRmxcHl5lT6Y3dNT3xAfHAA9cUnVsAAC%2bRmxcHl5lT6Y3dNT3xAfHAFr%2fAYscAAAW&fId=LgAAAADMJNzMj%2brsS4PO%2fGghaEMzAQC%2bRmxcHl5lT6Y3dNT3xAfHAA9cUnVsAAAB

As is to be seen, contain this address two IDs. The first is the OWAId (RgAAA...). I can generate this with the following code:

ConvertIdType IdConverter = new ConvertIdType();

IdConverter.DestinationFormat = IdFormatType.OwaId;

IdConverter.SourceIds = new AlternateIdType[1];

AlternateIdType IdToConvert = new AlternateIdType();

IdToConvert.Format = IdFormatType.EwsId;

IdToConvert.Mailbox = sender;

IdToConvert.Id = message.MessageType.ItemId.Id;

IdConverter.SourceIds[0] = IdToConvert;

ConvertIdResponseType cIDResponse = svc.ConvertId(IdConverter);

But how can I generate the seccond ID (LgAAA...)?

但是此方法已测试, OWAId 获取不对, 

谢谢.

Answer 1

另: Creating OWA URL from EWS Response http://www.mombu.com/microsoft/exchange-server-development/t-creating-owa-url-from-ews-response-632192.html

byte[] prEntryID = System.Convert.FromBase64String(miMailboxItem.Item Id.Id);
byte[] owaLink = new byte[72];
owaLink[0] = 70;
owaLink[71] = 9;
int owaval = 1;
for (int sl = 43; sl <= prEntryID.Length-1; sl++)
{
owaLink[owaval] = prEntryID[sl];
owaval++;
}
xrXmlWritter.WriteElementString("link", "https://" + snServerName + 
"/owa/?ae=Item&t=IPM.Note&id=" + 
Server.UrlEncode(Convert.ToBase64String(owaLink))) ;

该方法也不对.

Answer 2

Hi Harvey,

这里有一个方法可以获取一个OWAID。

   //Get the OWA Id     
public String GetOutlookOwaId(EmailMessage message, ExchangeService ser)  
   {        
 AlternateId ewsId = new AlternateId(IdFormat.EwsId, message.Id.ToString(), "[e-mail]"); 
 AlternateIdBase owaId = ser.ConvertId(ewsId, IdFormat.OwaId);         
return ((AlternateId)owaId).UniqueId;  
   }     

以上方法来自英文连接，你可以参考一下。

Answer 4

hi, jack.

由于我使用的 ExchangeServiceBinding 这种方式来获取的《 

下面这个类似

ConvertIdType IdConverter = new ConvertIdType();

IdConverter.DestinationFormat = IdFormatType.OwaId;

IdConverter.SourceIds = new AlternateIdType[1];

AlternateIdType IdToConvert = new AlternateIdType();

IdToConvert.Format = IdFormatType.EwsId;

IdToConvert.Mailbox = sender;

IdToConvert.Id = message.MessageType.ItemId.Id;

IdConverter.SourceIds[0] = IdToConvert;

ConvertIdResponseType cIDResponse = svc.ConvertId(IdConverter);

Hi harvey,

下面的方法不知道你有没有尝试过。

private int GetUnReadMailCount()
        {
            string url = "http://10.10.10.254/exchange/"; //指定Exchange服务器地址

            System.Net.WebResponse Response;
            System.Net.CredentialCache MyCredentialCache;
            string strUserName = UserName; //指定登录的用户名
            string strRootURI = url + strUserName; //得到要访问邮箱的WebDAV地址
            string strPassword = PassWord; //指定该用户的密码
            string strDomain = "unique.com"; //指定域名
            string strQuery = "";
            byte[] bytes = null;
            System.IO.Stream RequestStream = null;
            System.IO.Stream ResponseStream = null;

                // Create the HttpWebRequest object.
                Request = (System.Net.HttpWebRequest)HttpWebRequest.Create(strRootURI);
                // 指定HttpWebRequest的身份凭据，此处为关键所在。如果使用之前
                // 创建的MyCredentialCache，则这个身份凭据是可以从Web服务器传递
                // 到Exchange服务器的，但是这样带来的问题也很明显，就是不能够自
                // 动获取当前登录到域的用户的身份。即便已经成功登录到域，那也只
                // 能通过form再次输入用户名密码。因此，我在这里用的是
                // Request.Credentials = CredentialCache.DefaultCredentials，
                // 这样便可以获得当前用户的凭据，但是这样带来的问题便是上面提到的
                // 身份凭据无法传递的问题，解决方法请关注下篇文章。
                Request.Credentials = MyCredentialCache;
