Outlook 2003 password prompt with Exchange 2007

[Curlergrrl]

I am in the process of deploying an Exchange 2007 server in an existing
Exchange 2003 environment. Exchange 2007 is running on a Windows 2008 Server
(standard edition), with SP2. All clients are running Vista Business with
Outlook 2003. I have moved one mailbox to the new server and am having a
rather strange little problem. When I open my Outlook 2003 client, the
mailbox opens fine, no problem. However, about 15-30 seconds or so after the
mailbox opens, I get a password prompt asking for a password to connect to
the new (Exchange 2007) server, where the mailbox resides. Once I enter the
user's password, the prompt goes away and doesn't reappear until the next
time I close and open the mailbox. I am logged on to the workstation with
the same user name and password as the mailbox, so there's no reason I can
think of for this prompt to come up. I've tried creating a new Outlook
profile and also changing the authentication methods in the Outlook profile,
but nothing seems to make a difference. I've also done a little searching on
this topic without finding anything to give me a clue as to the cause of
this particular problem.

This is all connected locally, so there's no OWA or Outlook Anywhere action
going on here - it's a straight private LAN connection.

Any help would be appreciated. I really don't want my users to have to type
their password each time they open Outlook.

Exchange 2007 is in the same forest and organization as the Exchange 2003
server, correct?

Yes. I have discovered (to my surprise and confusion) that this only seems
to happen on my administrative workstation, where I am logged on with domain
administrator and Exchange Full Administrator permissions! Doesn't make any
sense to me, but at least it doesn't seem to affect the regular users...

You shouldn't mail-enable administrator accounts because you might allow a
potential virus sent through e-mail to have the keys to your kingdom.
Security best practice is to separate your personal mailbox-enabled account
and your administrative account.

Administrative accounts have some explicit denies in rights that might be
interfering with your client operation, but I can't say without a lot more
information, sorry.
