Outlook 2002, POP3, Active Directory authentication

[Peter]

Hi,

I have 2 mailboxes on our Windows Server 2003 POP3
server - one is my personal and one is general "admin"
mailbox, from which I supposed to read emails.

POP3 is using Integrated Active Directory authentication
and requires SPA. Each mailbox has corresponding AD user,
one is me and one is dummy "admin" user.

I'm trying to read mail from both mailboxes using Outlook
XP SP2, insatlled on my Win XP pro workstation.

I have set up 2 Accounts in Outlook, specifying
everything the wizard asked for. When I run test
Settings, both accounts test fine, finding POP3 and
logging into it.

However when I'm trying to retrieve the messages, I am
receiving messages corresponding to the current session
credentials only. I.e. if I am logged into my workstation
as me, I'm getting all the emails from my mailbox, if I
log off and back on again as admin, I am getting his
emails, but not mine.

Is there a way to retrieve messages from both accounts
when I logged in as myself, because it's a bit of pain to
log on and off all the time...

I would greatly appreaciate any suggestions or hints.

Peter

Peter I have started to do some logging and trying to make sense out this one
I did find a work arround by selecting the message option for a delivery receipt

Anyway I am documenting this in my post and hope to find the root cause soon. In the mean time I advice you to turn on the logging option as well for more details

See my post for how to and... where to find the log file ..

In my case everything worked as "expected" - i am getting delivery
notification but not the message.

Hi Bart,

I kind of make it working for me. However I am still convinced that there is
a logical "bug" in Outlook.

First, I've noticed this. When I try to send-receive, one of the accounts
(admin@, the one which had troubles) initially fails to connect to pop3
server. It pops-up window asking me to provide password (and domain) log on.
Before, I was chosing to hit "cancel" and although in subsequent
sends/receives the task was reported as completed sucessfully, nothing was
really downloaded.

For once I took trouble to provide the password (still leaving the domain
name blank) and it worked, i.e. all messages were downloaded!

This behavoir was described somewhere, i.e. to prevent "denial of service"
attacks pop3 servers reject simultaneous connections from same ip address.
The advise given was de-synchronise delivery putting the accounts in
different groups.

I've done that (putting admin@ in separate group with different delivery
schedule) and got back to square one! No pop-up window appeared asking me to
log on to my admin@ account, send-receive task was completed successfully
and no messages were downloaded. More, it worked even when I left the
password field in account settings blank! I also tried to leave the password
field blank for my main account (the one I am currently logged in into
workstation). It worked perfectly well downloading all my mail! Yet more
mysterious is my main account's mail was downloaded when I executed
"de-synchronised" task for admin@.

All this pictures the following scenario for me. Outlook choses to ignore
account name and password provided in account settings and sends Windows
logon credentials to pop 3 server. When I configure 2 accounts, one of them
initailly denied access. Outlook "thinks" this is because credentials are
wrong and asks me to provide correct ones. When i do this, Outlook correctly
uses "default" credentials for the main account and newly provided
credentials for the other one, all mail got delivered correctly.

The only inconvenience with this scenario is that I have to type in
account's password once when outlook starts. Which is not too much trouble.
However it would be nice to hear explantions of this behaviour from
Microsoft. Even "behaviour by design" would do

Regards,

Peter

Peter that is good news (sort of..

While my post did not seem to get any more follow ups not even from the MVP.. I decided to post it once again a bit more descriptive in the subject. "Outlook 03 not able to send mail to accounts on same mail server"
I have also started the discussion with the admin from the mail server. Initialy I don't think he belived it but now that I also have somebody else confirming the exact same behavior he I think might be reviewing the server side logs. He had not seen this behavior with earlier versions of OL and had not heard from any other clients

I am convinced this is a bug of some sorts and am determined to find out the root cause
