SBS 2008 POP3 Internet Security Warning

Hi Guys

Exchange 2007 is working perfectly, Popping the mail in and the clients are configured on the exchange accounts which are able to send and receive internally and externally.
The problem is that a user that is away from the office has now had his notebook stolen. Now i need to setup his email and the exchange accounts can only be setup in the office or thru VPN which are not possibilities.

So i configured POP3, all standard setup except that the outgoing mail is on 587 and TLS authentication is required. I setup a test account on a users outlook and When i test these settings all goes thru perfectly. Except that an Internet Security Warning Pops up and says ' the sever you are connecting to is using a security certificate that cannot be verified. A certificate chain processed but terminated in a root certificate which is not trusted by the trust provider.
I view the cert and it is correct except for the Issuer which is my server instead of Go Daddy.
If i click yes everything works ok except when i reopen outlook then it trys to re-establish the trust again.

Is there a way to fix this issue?

Hi Guys,

I've sorted it out. Checked Basic authentication only on the receive connector.

Thanks for the help!

yes, you will need to set up your exchange server to use your godaddy certficate. Also, the user needs the root certificate installed as trusted.

here is a good video explaining the process for 2010, it's for a different provider, but the steps are the same :)

Thanks Azhrei1:
Questions: Im a little lost in 2010  where would i go to do it in 2007.
So it wont change anything or stop anything on the users that are already setup to use exchange internally and externally via Exchange proxy?

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

ah sorry, I answered a 2010 question just before so I was in the wrong mindset, here is another tutorial for 2007:

no movie there though :(

Btw, make SURE you change this:

Enable-ExchangeCertificate -Thumbprint [thumbprint] -Services "SMTP, IIS"
 
into this for POP3 to use the certificate:

Enable-ExchangeCertificate -Thumbprint [thumbprint] -Services "SMTP, IIS, POP3"

:)
