Outlook 2003 over RPC/HTTPS always ask password

[Vit Knyshevich]

Hi,
Outlook 2003 cannot open mailbox over RPC/HTTPS, athough it works fine over
RPC. I performed Q833401 completely but Outlook always ask for password. I
tried to connect over internal network. Why it could happens?

Best regards,
Vit Knyshevich.

Double check the settings on the web site against the document.
Outlook using RPC over HTTPS will ask you for the user id and password
but should let you in once the credentials are provided.
You'll find it's probably the web side, not the Outlook side that's
incorrectly configured.

Thank you Mark. I checked out again. I've found that it happens when I try
to open mailbox from another site (or using account of user of another
domain? I'm not sure). Sites are connected by VPN. When I open mailbox from
server's local network it works fine, I checked out it by outlook /rpcdiag.
But it doesn't matter because it was just for testing purposes.

Unfortunately I cannot open mailbox through internet service provider too.
Mailbox server is inside internal network and it's published by ISA on
another server. OWA, OMA are published and work fine. I try to publish /rpc/
virtual folder of mail server (I use case "rpc proxy and mail are on the
same server") exactly as OWA and OMA, but Outlook cannot open box. It very
long connects, then asks for credentials, then very long connects again,
then suggest to work offline.

I'm not sure if RCP/HTTP works by publishing /rpc/ folder. I checked out,
https://server/rpc/ replies as it described in
http://support.microsoft.com/default.aspx?scid=kb;en-us;833401#10.

Best regards,

I've found what it was. I use per-machine proxy settings, so even I
uninstalled MS Firewall Client and removed proxy settings in IE, Outlook
still tried to communicate with proxy server opening proxyserver:8080. I
removed per-machine proxy settings and problem is gone. Unfortunately,
Outlook doens't event tries to connect over rpc/https (443), it tries to
open port 135 only, but it's another story...
