Property Value

The unique ID of this message. This is used for accessing this message in a manner which cannot be affected by server-side removal of other messages (The Object.Id property does not guarantee this). The uniqueness of the identifier varies depending on the mail protocol used for this message (ex. IMAP UIDs are guaranteed unique on a per-mailbox basis only).
