Outlook 2010 cannot use Secure Password Authentication

Question

I am the administrator of the server running Microsoft Windows 2003 Server POP3 service since 2008. It hosts my email account. Nobody but me manages the settings of the server and the client side. Until the moment I decided to install Microsoft Outlook
2010 as a client there was Secure Password Authentication working between Outlook 2003 and Windows 2003 Server. After installing of Outlook 2010, when I try to sync, the SPA authentication doesn't work. Nothing is changed on the server side.
Enabling the SPA authentication on the both sides results a communicaton problem between Microsoft Windows 2003 Server POP3 service and Microsoft Outlook 2010 client. When I disable SPA on both sides the connection works but password is sent
as plain text. Actually I started a discussion on
http://answers.microsoft.com/en-us/office/forum/office_2010-outlook/outlook-2010-cannot-use-secure-password/66dafd66-1b00-43b5-96fb-b8a26254fc77 but I didn't receive an answer with a solution.

Snefels,
This is actually a known issue that Outlook 2010 doesn't work well with Windows Server 2003 POP services.
Here is the blog post for the issue:

If you read the comments below, you'll found that some readers' shared some workaround/solutions, which reportedly works for others. So you might want to have a look.
Disable SPA on the Windows 2003 POP3 server and do the same in Outlook 2010 POP setup.. using the full email address, "[email protected]" instead of just doug (if using the Secure Password Authentication).
