I have a Small Business 2008 Server at home with Exchange 2007 tied to my RoadRunner account. Setting up my new EVO to use Exchange a month ago was a breeze and I haven't had any problems with it until this morning. When I turned my phone on, I kept getting a trusted certificate error over and over. I am using a self-signed certificate on my server -- which I thought would give me a problem when I initially configured it, but it didn't. I was expecting to have to install the certificate manually. After a few minutes, the message went away and I started receiving mail again. I haven't done anything major on the phone that might cause that, like installing an update. Does anyone else use the same thing and ever experienced the same message?
