How to connect exchange server using .Net

Hi,

I try to connect to Exchange server using MAPI. I need to access a special
user inbox and read all his new mails.
The code I wrote work good, but I get my inbox instead of the user I need.
Here the code :

MAPI.Session objSession;

MAPI.Folder objFolder ;

MAPI.Messages objMessageList;

MAPI.Attachments objAttachmentList;

MAPI.Attachment objAttachment;

MAPI.MessageFilter objFilter;



string strUser = "Scott";

string strPass = "123456";

string strServer = "MAILIT";

try

{

objSession = new MAPI.SessionClass();

objSession.Logon(strUser, strPass, true, false, 0, true, strServer + "\n" +
strUser);

//For Inbox

objFolder =
(MAPI.Folder)objSession.GetDefaultFolder(MAPI.CdoDefaultFold erTypes.CdoDefaultFolderInbox);

objMessageList = (MAPI.Messages)objFolder.Messages;

objFilter = (MAPI.MessageFilter)objMessageList.Filter;

objFilter.Unread = true;

objFilter.Type = "IPM.Note";

if ((int)objMessageList.Count > 0)

{

MAPI.Message objMessage;

for(int i=0;i<(int)objMessageList.Count;i++)

{

objMessage = (MAPI.Message)objMessageList.GetNext();

MessageBox.Show(objMessage.Subject.ToString() + "\n" +

objMessage.Sender.ToString() + "\n" +

objMessage.TimeSent.ToString());

}

}

if (objSession != null)

objSession.Logoff();

}

catch (Exception ex)

{

MessageBox.Show(ex.Message);

}


Why I get my inbox instead of Scotts inbox ?

Thanks,

David

Re: How to connect exchange server using .Net

Hello David,

MAPI is not supported from a managed process (it's memory management
collides with the .NET garbage collector).

Your are better of using WebDAV (in case of Exchange 2003) or WebServices
(in case of Exchange 2007) to access the folder.

I have plenty of information on my website (www.infinitec.de).

And here is the WebDAV reference on MSDN:
http://msdn2.microsoft.com/en-us/library/aa486282.aspx

Kind regards,
Henning
