Outlook 2007 Security Certificate is Invalid

BenthamLtd asked
Last Modified: 2012-05-09

I've just installed a new SBS2008 server into a new office.

When I was configuring the server, using the sbs console I set the Internet Address to mail.testingdomain.co.uk  so I could test the routing of email.

Now that I have installed the server, I cannot seem to get rid of mail.testingdomain.co.uk.

I ran the SBS wizard on the Admin Console, entered the new name, but it errors before completing.
And all Outlook 2007 clients get this error when opening outlook.

They still receive email, but they have to acknowledge this error twice before it will go away.

How can I change this to point to my new domain, remote.newoffice.com
