When I try to access my exchange account away from the office I get the

following messsage:

"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 xxxx.xxxxxxx.com (error code 8)"

I updaed the certificate but still having the problem

How did you update it? Is the cert from a reseller or created by the

exchange server/proxy server? If its self created you need to publish it on

the local computer and trust it.

Is your company using a trusted certificate or a self-signed certificate?

If it is a trusted certificate, check Windows Update and make sure you have

the update for root certificates applied. When using Windows XP, you'll see

this update when choosing Custom.

Hi.

I'm also getting the certificate error (error code 8).

Am guessing i need to publish the certificate on my local computer.

I'm using windows 7, on my laptop.

Can somebody guide me here, how to run the publish the certificate ???

The error message should have a button to view the certificate and when you open tp view it, there will be a publish button. That should fix it for you. <fingers crossed> >

:(

The publish option is not available !!

In my internet explorer , I clicked and view the certificate.

But there is no option to publish ....

What to do ??
