POP3 problem with encrypted connection using Windows Vista

F

Frank

I have an email acount with my employer, which I use without a problem
running Outlook 2003 with Windows XP SP2 and IE7, as a POP3/SMTP account. My
employer uses a certificate for the server, which is the same for the
intranet site.
Now on my new notebook I want to run Windows Vista with Office 2007 (i.e.
Outlook 2007). I have the certificate installed, and can go to the intranet
set without problems. I enter exactly the same email acount settings as
before, which include:
- 'My outgoing server (SMTP) requires authentication' / 'Use same settings
as my incoming mail server'
- 'Server Port Numbers' specified for both incoming server (POP3) and
outgoing server (SMTP).
- SSL encrypted connection for both incoming and outgoing server

But when I test the account with Outlook 2007 it gives the following messages:
"Log onto incoming mail server (POP3): Your server does not support the
connection encryption type you have specified. Try changing the encryption
method. Contact your mail server administrator or Internet service provider
(ISP) for additional assistance."
and
"Send test e-mail message: Your server does not support the connection
encryption type you have specified. Try changing the encryption method.
Contact your mail server administrator or Internet service provider (ISP) for
additional assistance."

If I run Outlook 2007 with logging enabled it shows the following:
2007.07.20 15:36:10 (e-mail address removed): UploadItems: 0 messages to send
2007.07.20 15:36:10 (e-mail address removed): Synch operation completed

2007.07.20 15:36:10 (e-mail address removed): Synch operation completed

I also tried using the Vista Windows Mail, and it gives me the following
error:
"Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Account: 'xxx', Server: 'aaa.bbb.ccc.ddd', Protocol: POP3, Port:
995, Secure(SSL): Yes, Error Number: 0x800CCC0F

The strange thing is that I can get it to work with the mail-monitor gadget
that is part of True Launch Bar (http://www.truelaunchbar.com/), still
running Windows Vista.

I have tried changing some advanced IE7 settings regarding encryption, tried
enabling disabling Windows Firewall etc. but nothing helps.

(I have changed the email-address and ip-address, for privacy reasons).

Hope someone can help me.
Kind regards
