Do you know if the outlook was updated in those machines ?

Can you check if there is any update or higher version for the same add-in.

What does the add-in do ?

Once removing the add-in , close OL ,  go to this registry location

HKLM/Software/Micrisoft/Office/Outlook/Addins/YourAddin

HKCU/Software/Micrisoft/Office/Outlook/Addins/YourAddin

and remove the add-in entry (if found).

Open OL , install the add-in again and check
