we've got some Problems with Outlook-Authentification (2003 RTM, SP2 and SP3).
As designated for HMC we're using RPC-over-HTTPS.
When a user enters a wrong Password, he is not prompted to re-enter the password. Instead Outlook goes into Offline-Mode silently (and then we get the calls, why the user isn't able do receive mails).
Can you somehow force OL to give a Message when it goes to offline-Mode?
Another issue is, that the password can't be saved in OL. You can save the password using Control Panel -> Users -> Stored Password and then adding an Account for the whole HMC-Domain.
I think, this two issues have the same reason: Outlook has to authenticate two times: one time for the Exchange-Server, but before on the RPC-Proxy. When the authenitfication fails, it can't contact the Exchange-Server. This is interpreted as a network issue,
so OL goes offline-mode. And when you try to save the password, OL saves the password for the Exchange Server, not for the RPC-Proxy, so the Password-Saving doesn't work correct.
What do you think about my interpretation? And, very important: How are you dealing with this? I think it's a Problem, everybody who uses HMC has.
A solution could be to disable Authentification on the RPC-Proxy, but that's also a question of security. Anybody tried it?

I'm using Outlook 2007, after I enter wrong password many times, outlook goes into offline mode, but it give me a "Need Password" warning on the right bottom corner.
RPC over Https uses basic authentication, so even you can't see 'remember my password' option. However, you can save user/password info using Control Panel -> Users -> Stored Password, but it can only remember your user account. To archive this, first, change
your RPC proxy authentication from basic authentication to NTLM authentication, then go to Control Panel -> Users -> Stored Password, add account/password info for whole HMC domain (ex. *.fabrikam.com - internal FQDN name).
Now open Outllook, it will not asked for credentials again.

thank you for your Answer.
I knew allready how to store the password (and wrote it). But this is not much help: if the password is changed in the HMC-AD and not adjusted in the Stored Passwords, OL stays in Offline-Mode without telling the user about the wrong password (this was
my basic problem - Users get no message, when their pwd is wrong, OL goes to Offline-Mode silently). The other drawback: the method with the Stored Passwords is too complicated, we can't ask our customers to use it.We also can't ask our customers to migrate
to OL 2007.
We're using NTLM-Authehtication, not Basic. I think DepWT reccomends it.

Aha, I understand.
Seems there is no way to work around this.
