Trying to connect Outlook to remote SBS 2003 Exchange Server using RPC over HTTP.  Keep getting certificate error message.

When I try to access remote in IE 9 there is no option to install/trust certificate.  I have tried opening IE 9 as an administrator still no joy.

What next to get rid of this blasted error?

Thanks.

What's the error please?
Have you tried adding the site to your trusted sites?

Internet Options -> Security -> Trusted Sites

Another thing to look at is whether you have a certificate associated with the site added to your certificate stores. You can check this through the MMC certificate snap-in.

When Outlook tries to connect you get the logon screen then after entering credentials Outlook gives the error;

"There is a problem with the proxy server's security certificate. The security certificate is not from a trusted certifying authority.  Outlook is unable to connect to the proxy server remote.company.com (error code 8)"

Made site a trusted site in IE9 - still comes up with a certificate error

IshaanRawat - thanks for your detailed information.

I'm hoping there's an easy way round this because I have about six remote users who need to connect their Outlook this way.  After all I know the server is trusted.

You will need to install the SSL cert if its self-signed.  I don't know why you are unable to install it from IE9 though.  First, be sure that you run IE "As Administrator".  Then you just need to click on the LOCK icon in the address bar and then "view certificate" to access the Install button.

If you don't see the LOCK icon, either expand the address bar, or use the regular menus and go to VIEW > Security Report.  Of course you need to be connected to your server's OWA or RWW site via https for this.

If you still don't see anything, you can export the certificate directly from the server and then install it on the remote machine.

Hi TechSoEasy,

Got there at the same time.  Here's what I found which is effectively what you are saying.

The thing that threw me was there was no lock icon.  The article correctly mentioned the address bar also like you.  This IE9 is drivin' me crazy!
