Manually removing Exchange autodiscover (SCP) entries from Active Directory

Welcome to our webpage on how to remove Autodiscover SCP from Active Directory. If you are an IT administrator or a system engineer, you may have encountered Autodiscover SCP, which is a service connection point in Active Directory that allows Microsoft Outlook clients to automatically discover Exchange Server settings. However, there are situations where you need to remove Autodiscover SCP, such as when decommissioning an Exchange Server or migrating to a new email system/service. For example, we were migrated from an on-prem exchange environment to O365 but needed to keep our existing Exchange server online and available so we could have old email available for when issues arose or something didn’t replicate correctly/completely. The local Outlook client (pretty much any version) will automatically connect to the Exchange server listed in AD rather than the one you specified when you setup the Outlook profile (at least that was the case when I was dealing with this). So even if you use an external address in the server config, after you open Outlook it’ll automatically revert you to the Exchange server listed in AD.

Removing Autodiscover SCP requires specific steps to ensure that your Exchange environment functions correctly. In this guide, we will provide you with step-by-step instructions on how to remove Autodiscover SCP from Active Directory.
