Mail's attachement's filename is 100000000000000.doc for chinese filename

Question

When I recieved a email with a chinese filename attachement form Exchange server(IMAP download). The filename will change to something like 100000000000000.doc
No matter I change the text code in the "Message" coloumn, the filename still keep the 100000000000000000.doc.
But in the meantime, the same email recieved by Entourage, the attachement filename will be normal in Chinese chracter.
Please help me about this, thank you.

Hi Daniel,
As i know, there is a property of ExchangeService ,
this is the detail info:
The application can change the ImpersonatedUserId property
to impersonate multiple accounts
This is the example:
void ImpersonationSample()
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.Credentials = new NetworkCredential(appName, appPassword, emailDomain);
service.AutodiscoverUrl(appEmail);
service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, user1Email);
Folder newFolder = new Folder(service);
newFolder.DisplayName = "TestFolder1";
newFolder.Save(WellKnownFolderName.Inbox);
service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, user2Email);
Folder newFolder2 = new Folder(service);
newFolder2.DisplayName = "TestFolder1";
newFolder2.Save(WellKnownFolderName.Inbox);
