In a Windows 2008 domain with 25 pc's, we run Exchange 2007 std and Office 2007 on all Pc's except one HP Laptop running Office 2010.
In the Office 2010 laptop, when he opens email, he received a security warning. When we installed the server, we created a certificate and recreated it a few weeks ago. Now this one user receives the security every time he opens outlook. I'm wondering if I need to purchase a certificate from godaddy or other company to resolve this pervenantly.
Attached is a pdf showing the error.
