How do I stop the annoying Security Alert that pops up for Outlook 2010 clients when connecting to our newly installed Exchange 2007 server?


I have tried this guide... to no avail...

although I used our FQDN instead of the public URLs as I have not setup public access yet.

You need to configure the server correctly.
Do you have other Exchange servers? If so then you can reconfigure Autodiscover on the new server to point users at the old server.

set-clientaccessserver servername -AutodiscoverServiceInternalURI https://host.example.com/Autodiscover/Autodiscover.xml

where servername is the name of the new server and host.example.com is the address on the existing server.

The other exchange server is 2003. As far as I know it doesnt have an autodiscover VD?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

As Exchange 2007 is over six years old I kind of presumed that you were setting it up because you had an existing one. Otherwise why not deploy something a bit more modern?

Either way, you are going to get the prompt until you get your SSL certificates sorted out. That is because Outlook 2007 and higher is querying Autodiscover all the time and now there is something to answer those queries.

OK, so how do I get my certificates sorted?
As in... what system needs a certificate, do I have to go to vendor or can I generate one from a local CA?

I wouldn't recommend using an internal CA unless you are going to have control over 100% of the clients accessing the server. I don't just mean Outlook, but ActiveSync and OWA.
A trusted certificate is $60/year and will save a lot of headache.

I have a section on my web site for doing the SSL certificates: http://semb.ee/2007ssl
