Hi Tim,Trying to understand why you are trying to configure OL on a Domain Controller. Now when it is doing the auto discovery and getting your user ID from the AD, so I am sure initially it is getting the update from AD. See if the windows firewall isswitched on the domain controller. Also check if the AV or the some other application is doing this.Raj

You might also test autodiscover settings byholding down the CTRL key, right clicking the Outlook icon in the notification area (system tray), and then select Test E-mail AutoConfiguration. See what errors you get, if any. I suspect it may be an issue with URL's or misconfigured Autodiscover. Shaun

Hi Tim, First, we don't recommend you install/use Outlook in a DC. Installing other applications in the DC will affect the performance/function of DC and it will be a hurdle for disaster recovery. Keep a clean DC is very important. For your issue, if you insist to use Outlook in the DC, please manually configure the profile. After checking name, please ignore user name/password typing and go to the more settings configuration, in the security tab, change the authentication method to NTLM authentication. Then test the issue again. Thanks, Elvis
