outlook / read receipts

[Mike]

Hi,

We run Outlook 2002 (sp2) against an Exchange 2000 server.

When a user requests a read receipt, they expect to get
one .. however in Outlook (by selecting: Tools, Options,
Email Options, Tracking Options)
the recipient has the option not to send one etc..

Is there any registry change that can be applied so this
option is disabled ??
Can I set a Group Policy to disable it ??


Any help appreciated

Thanks,
Mike
