Outlook 2013 Meeting On behalf of someone else

Hi,

I want to know if it's possible to avoid that a meeting scheduled by a user on behalf of other appears to the attendees with the title "user1 on behalf of user2".

I would like that the attendees receive the meeting invite as it is coming from user2, though it has been sent by user1. User1 has full permission to user2 calendar and manages it.

Is it possible? Thanks.
