I should have been clearer I want receipts from users. I know this can be
configured in  email tracking options to auto send, read receipts and
delivery receipts upon request. I have managers that expect action taken on
certain emails. These are sent with delivery and read receipt requests,
however the user if prompted can ignore request or if not prompted change
the options setting so that he is. Is this also configurable from group
policy so that a user would require admin to local machine to tamper with.
You don't need Exchange to be able to use group policy to set registry
values:

Request a read receipt for all messages a user sends
Key: HKCU\Software\Policies\Microsoft\Office\11.0\Outlook\Preferences
Value name: ReadReceipt
Value type: REG_DWORD
Value data: 1 = Enabled, 0 = Disabled (default)

Request delivery rcpt for all msgs a user sends (Exchange only)
Key: HKCU\Software\Policies\Microsoft\Office\11.0\Outlook\Preferences
Value name: DeliveryReceipt
Value type: REG_DWORD
Value data: 1 = Enabled, 0 = Disabled (default)

You would, of course, need to be set up so the end user doesn't have
administrative access to the machine.
