Answer 1

Use Namespace.GetItemFromID. Note the second parameter (store id) is optional. You can omit it if the store in question was already touched by Outlook is in the current session. If not, Outlook will raise the "unknown entry id" exception. If the store entry id is specified, Outlook will open it first, and the store provider will have a chance to register its entry ids with the MAPI system.

set App = CreateObject("Outlook.Application")
set NS = App.GetNamespace("MAPI")
NS.Logon
set Msg = NS.GetItemFromID(EntryID)
MsgBox Msg.Subject

Answer 2

For C#:

var ns = OutlookApp.GetNamespace("MAPI");
var item = ns.GetItemFromID(entryId) as MailItem;

Where OutlookApp has Microsoft.Office.Interop.Outlook._Application type.
