New Post: how to call 2003 version api to load auto complete stream?

HI,

I know in 2007 or later, we can use below code to load auto complete stream:

Microsoft.Office.Interop.Outlook.Application oApp = Globals.ThisAddIn.Application;
Microsoft.Office.Interop.Outlook.MAPIFolder inboxFolder = oApp.GetNamespace("MAPI").GetDefaultFolder(OlDefaultFolders.olFolderInbox);
StorageItem storage = inboxFolder.GetStorage("IPM.Configuration.Autocomplete", OlStorageIdentifierType.olIdentifyByMessageClass);
PropertyAccessor propertyAcc = storage.PropertyAccessor;
byte[] got = propertyAcc.GetProperty("http://schemas.microsoft.com/mapi/proptag/__0x7C090102__");


But for 2003, which mapi can we call, could you help and give a code sample?

Thanks in advance.
