Re: "Send as" and SBS Domain Power User



Hi Nathan,

information you have provided describes expected behaviour. I have no
problem with that and fully understand how to set up delegates and level of
privileges they have.

Now, I need to clarify where I see the problem.
1. I create NEW SBS user using standard user template.
2. This NEW user is NOT a delegate for any of the mailboxes on exchange.
3. At this stage NEW user cannot send on behalf or send as any other user.
4. As soon as I add NEW user to Domain Power Users group, NEW user can send
email from any mail box. Receiver of this email doesn't see "on behalf of".
Email looks like it came from user XXX or YYY or Administrator.
This is why I said that Domain Power Users seemed to have "send as" rights
to all mailboxes in SBS 2003 domain. Yet, this "send as" permission is not
visible anywhere in security properties of exchange objects.
I have tested this behaviour on three different SBS 2003 sites. I will try
on few more in days to come as time allows.

I hope, this time I made my description clearer.

Cheers,
