Outlook 2007 problem - network lockout - PLEASE HELP

[Sergej Prokoviev]

I didn't get an answer from last week, so I am re-posting this:

I recently installed Office 2007 Pro on one of our workstations, which
runs on Windows XP Pro SP2. Our email runs via an app on a server I am
connecting to through the very simple POP3 service Server 2003 came
with. When you create a mailbox, it creates a local user with it (with
a password that does not expire). That local user (SERVERNAME\123) has
the same name as my network logon (DOMAIN\123). I am not an admin on
either machine, just a poweruser on the workstation and a normal user
on the server that is only allowed access to the mailbox.

It used to work fine with Outlook 2003. Now that I have installed
Outlook 2007, it keeps trying to log me on with my network credentials
to the server and ultimately locks me out on the domain controller if I

have Outlook up ("unknown username or password"; "account locked out").

I did check the registry on the workstation, which was missing one key
that Microsoft said I needed. It has been added. However, that did
nothing to fix it. It won't let me unistall TCP/IP as the local admin.


Any thoughts? I'll have to revert back to 2003 if I can't fix it.


Thanks!

Have you tried it with a new mail profile already?

Also see if you can reproduce this behavior when you logon as a different
user.

Thanks for the prompt reply. I will try and recreate the mail profile
as described in the article you mentioned. However, when I recreated
the same scenario on another computer with the same setup, only a
different user, the exact same thing happened. It seemed to check every
so many minutes for mail, and in doing so locked out the network user.
The local mail user on the server is fine.

Any more thoughts?

Thanks a bunch!

I just created another mailbox that has no associated network user.
Here is the failure audit:

Event Type: Failure Audit
Event Source: Security
Event Category: Logon/Logoff
Event ID: 529

Then, right after that, I see this:

I honestly don't think that it has to do with the local machine, but
with the way Outlook2007 talks to the server. Please help!
