Outlook 2007 asks for password on Outlook Anywhere but Outlook 2010 is ok

Exchange 2010 Version: 14.02.0247.005

2008 R2 Enterprise

Outlook 2007 persistently asks for password on Outlook Anywhere and even if the details are enter it's not accepted as been correct but Outlook 2010 works ok.

I've tried changing the following key HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\RPC to 1 as per http://support.microsoft.com/kb/956531 but without success.

Found a solution for now.

In email account on Outlook 2007, advanced settings, proxy settings. Untick Only connect to proxy servers that have this principle name.........

The principle name is different although the new email domain is in the certificate as an alternative name.

Good 2 know you found solution

This pointed me towards the fact that in Outlook the "Only connect to proxy servers with this principle name" was ticked and the domain is actually an SAN on the certificate so it stopped it from working.
