Outlook Anywhere Access RPC and Password issues

[boldweb]

Hi,

I had a copy of Exchange Server 2007 SP1 installed on Windows Server 2003 Enterprise x64 edition. I upgraded to Exchange 2007 SP2 and everything with clients still worked fine. Next I upgraded to Windows Server 2008 SP2 Enterprise x64 edition. Certain Outlook 2003 and 2007 clients that would originally use NTLM authentication over RPC HTTPS proxy now constantly prompt for a password and sometimes do and sometimes dont connect. I tried a number of fixes such as switching to Basic Authentication, and even disabling IPv6, however neither seemed to help. I also have some issues with IMAP clients connecting to a secondary Exchange 2007 mailbox.

Any ideas? Maybe I tried the wrong combination of fixes, but I would really like to get the RPC HTTPS proxy to work correctly and stay connected.

Thank you,

Stephen Daudell

I don't believe that upgrading the OS is supported once Exchange is installed. I know it wasn't supported under Exchange 2007 SP1.

thank you. would you know of any steps that can be taken to fix this issue? can a backup be made and then exchange uninstalled and reinstalled and then restored?

The server is just setup to use the built in Outlook Anywhere access built into Exchange Server 2007. Then outlook clients use the HTTP proxy option to connect.

HI,

Normaly when outlook constantly asks for a username and password over HTTPS, its dues to some kind certificate error.

In the outlook anywhere properties box on the outlook client does the msstd name in the proxy field match that of ther principle name on the certificate on the exchange server?
