We have a shared mailbox with multiple operators, collecting and inserting ERP sales orders. An order can be picked by different operators and be duplicated in ERP.

**Each e-mail has a unique `EntryID`, but after reading documentation, I can't understand if it is the same for all users of shared mailbox or if for each user there is it's own `EntryID`.**

If it is the same for all, I could log it in a shared file and check if it's done by EntryID.
