MobileItem.EntryID Property (Outlook)
Returns a String that represents the unique entry ID of the object. Read-only.
Version Information
Version Added: Outlook 2010
Syntax
expression .EntryID
expression A variable that represents a MobileItem object.
Remarks
This property corresponds to the MAPI PidTagEntryId property.
A MAPI store provider assigns a unique ID string when an item is created in its store. Therefore, the EntryID property is not set for an Outlook item until it is saved or sent. The entry ID changes when an item is moved into another store (for example, from your Inbox to a Microsoft Exchange Server public folder, or from one Personal Folders (.pst) file to another .pst file). Solutions should not depend on the EntryID property to be unique unless items will not be moved. The EntryID property returns a MAPI long-term entry ID.
