outlook 2013 the name on the security certificate is invalid or does not match the name of the site


I am using Hosted Email Exchange from iinet.net.au.

My outlook keeps showing this error a few seconds after loading.

Outlook error
The certificate is registered to:

Here are my account settings…

My DNS settings at NetRegistry…

My DNS settings on my in-house DNS server

If you are using a hosted Exchange platform then they are the ones who need to resolve the issue. That might be that you need to change some DNS records, if so, they should be able to tell you what those are. Trying to resolve this on your own isn't really going to work, because it isn't your environment and you cannot make changes to it.

I'd suggest you use a tool like mxtoolbox.net and fix your dns entries

Are you sure your system trusts the certification authority that issued your certificate?

David, Thanks.

I took a look at mxtoolbox.net but got a bit lost on this website.
Also couldn't make much sense of your post.

Justin F, how would I know that?

Justin F, I suspect it is the "name not matching" that is the problem (bust my humble opinion).
Sorry, I didn't pay attention to the URL you were going to in your screenshot.  Your certificate is issued by an AddTrust External CA which by default is trusted.  

However, your certificate is issued to "exchange.exchangemailservices.net" which obviously doesn't match mail.esuite.com.au which may be why your getting this message.

If I browse to exchange.exchangemailservices.net I don't get the certificate error, but of course when going to mail.esuite.com.au I do get the error.

Not sure if there is a workaround but I will see what I can find if no one else provides a solution.
Take a look at these and see if they will help.  Not sure how much access you have to the Exchange environment, but these seem similar to your problem.

I think you are right.  I put the same question to them.  We shall see what they say.
enigmasolutionsAuthor Commented:
You were correct.  I had to explicitly follow the DSN settings recommended from my ISP on BOTH my local DNS and my external DNS.  AND I had to carefully follow their recommended settings for OUTLOOK hosted email exchange.  Thank you all.
enigmasolutionsAuthor Commented:
ACTUALLY.  The real reason I had trouble was that mail.esuite.com.au was wrong.  My ISP recommended webmail.esuite.com.au.  For some really strange reason (no idea why) the mail hosting company didn't like my "mail.domain.com.au" setting.  I mistakenly thought for OWA it would be easier to just type mail.esuite.com.au.
