How Do I Turn Off Autodiscover?

[Bob L.]

We have started installing Outlook 2007 on a small network with Exchange
2003. We are starting to get certificate warnings about
autodiscover.mydomain.com, but we simply want to stop Outlook from
autodiscovering anything. How do we turn this off?

Autodiscover seems to be largely a waste in our case. Not only are we are
more than capable of typing in the server name (quicker than setting up or
troubleshooting autodiscover), but Outlook is trying to "discover" when the
user's account is already established - no need to discover anything.

And Exchange 2007 has never been on the network? The must be something
published on that address otherwise you don't get a certificate error either
(it means their has been a connection).

Check if it has been set as a policy in;
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Outlook\AutoDiscover
Value name: ZeroConfigExchange
Value type: REG_DWORD
Value data: 1

Or manually in
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\AutoDiscover
Value name: ZeroConfigExchange
Value type: REG_DWORD
Value data: 1

Robert,

Neither of those entries exist in the registry, and we definitely have never
considered installing or even looking at Exchange 2007. We only upgraded MS
Office from 2003 to 2007. The security warning is appearing because the DNS
for our domain includes a wildcard, so the autodiscover addresses actually
resolves to the same as www - our public web site.

We're not so much concerned about the security warning - we actully just
want to stop Outlook from trying to autodiscover altogether. We need to find
that "secret" checkbox or something!

Thanks,
Bob

HELP! I have the exact same problem.

autodiscover.mydomain.com (which does not exist)

The name on the security certificate is invalid or does not match the name of the site.​

​

We have Outlook 2007 and Exchange 2003

We have no use for autodiscover.

How can I disable or stop this message?

I'm having the same issue only my company is using Exchange 2007. We are a small organization &, because it was so easy to connect manually, we did not set up an autodiscover domain. Now we're getting the invalid certificate error & would really like not to.
Isn't there anyone that can tell us how to turn off this feature?

How to resolve

Reconfigure the users Profile manually versus the 1st dialog box you get in Outlook 2007, when you enter the email address, user name and password on the 1st page it forces Outlook 2007 to autodiscover.
