Can this error not be remedied using a self signed certificate?

depends are you using autodiscover to setup the connection, or are you using outlook anywhere? If so i would get a real cert you will have 0 headaches. They aren't that much for the time you will waste screwing with these self signed.

Use the SBS Manager to fix this.

Goto the network tab, then run the trusted certificate wizard to generate either a self signed (wont work on iphone/ipad outside of the network) or to generate a request to buy a trusted one. I use cheapssl.com as they are loads cheaper than godaddy.

check the name on the certificate matches exactly the internet domain name you have set in the network tab of sbs manager.

Once you ran the wizard and imported the cert, open a web browser on the server and goto this domain name and you should it.

Ok, for example

Our certificate is
remote.contoso.com, the server name in internet domain name is contoso.com

In our certificate we had these names entered
remote.contoso.com
owa.contoso.com
autodiscover.contoso.com
mail.contoso.com

Autodiscover and owa are being used.

"remote.contoso.com, the server name in internet domain name is contoso.com"

you mean that both are remote.contoso.com right as you cant have a blank entry for name?

You don't need all those other entries, for example owa is remote.contoso.com/owa

just to be sure your problem is the trusted cert you have used via the wizard isnt showing up when you goto remote.contoso.com. If its not what is if any ?

ok so when we go to remote.contoso.com the server comes up to a remote login page. The actually IIS page is at mail.contoso.com, so that would be the correct name for the cert then?
