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
