Differing UID between Get Exchange Mail Messages and Get Outlook Mail Messages activities

Hi Everyone,

As I have written a PS Script to set the category of an Outlook email, I noticed
that the UID of the MailMessage is not the same when using the Get Exchange Mail Messages compared to the Get Outlook Mail Messages. Both activities return a collection of Net.MailMessages objects, however when getting the the UID (item.Headers(“UID”)) the returned strings are not the same.

Is there an explanation for that, respectively a way to get the same UID with the Get Exchange Mail Messages activity?

Best regards
