After setting up the SRV record for Autodiscover service, launching Outlook 2010 or Outlook 2013, users may get the following warning.
Allow this website to configure user@domain server settings?
http://<autodiscover url>
Your account was redirected to this website for settings.
You should only allow settings from sources you know and trust.

To solve this problem, an administrator needs to add a registry setting for users.
I will use Group Policy Preferences to deploy the registry setting for users.
1. At DC01, log in as Domain Administrator.2. Launch “Group Policy Management Console“.3. Right-click the GPO which is assigned to the users using Outlook 2010, select “Edit“.

4. Expand “User Configuration > Preferences > Windows Settings > Registry“.5. Right-click “Registry“, select “New > Registry Item“.6. Next to “Action“, select “Update“.7. Next to “Hive“, select “HKEY_CURRENT_USER“.8. Next to “Key Path“, type “Software\Microsoft\Office\14.0\Outlook\Autodiscover\RedirectServers“.9. Next to “Value name“, type “<HTTPS server to which Autodiscover can be redirected>“.
Remark: The Key path is 14.0 for Outlook 2010 and 15.0 for Outlook 2013.
Example:imail.contoso.com
10. Next to “Value type“, select “Reg_SZ“.

11. Click “OK“.12. Close “Group Policy Management Editor” and “Group Policy Management Console“.
After assigned the GPO, launching Outlook 2010, users don’t get the warning.
Remark: If your environment is more than 1 Autodiscover record, you have to add each one.
