When we are comparing the "Prevent Copying" behaviour between notes client and iNotes. In Notes Client prevent Copying is working as expected. User is not able to reply, forward, copy the content of the emails but can only edit and save. But in iNotes prevent copying is not working as expected.
In iNotes, Recipient user tries to reply and forward the same email but he could not do so. Recipient user edits the emails and appends the text of the subject and body of the message and after that save and close the same email. Now recipient user again tried to forward, reply , reply to all but could not do so as per working of "prevent copying". But he is able to copy and paste the content of the email into new mail.
This functionality is seems to be working differently in notes client and iNotes whereas user should not be able to edit the mail when it is marked as "Keep Private"
In the outlook client using browser "Prevent Copying" behaviour is working as expected.
