In our setup of Samange, if a Requester creates a ticket on behalf of another user then auto populated list only returns users who have left the company.
If an admistrator attempts the same action then all users (current and former) are displayed.
Please see the attachment below for an example of this. In this case Sara Glen is returned for the Requester. Sara Glen left the business before we launched Samange and therefore has never logged into the system nor raised a ticket.
As an adminstrator a greater number of entries are returned (with active and former users)
When the same test is performed on the CC field only current users are returend (Sarah Glen does not appear on this list)
