Different ways to remove failed Exchange Server from AD

There are two native ways to remove failed Exchange Server, which we are going to discuss in this segment.

  • Via Exchange Management Shell
    It involves the replication of public folders and securing its data to a different location. But if stuck down by the error saying you need to remove public folders as well, run this cmdlet in the Exchange Management Shell run as administrator.

    MoveAllReplicas – sourceserver [server] -targetsever [server]

    After the successful execution of the above command, the Exchange administrator is required to run the following command to remove the legacy connectors.

    remove-routinggroupconnector [GUID]

    Provide the group ID of the connectors in place of GUID in the above command.

  • Via ADSIEdit
    Removal of Exchange Server from Active Directory can be performed using the native ADSIEdit.msc service by the Exchange Server as it allows editing, modifying, and deleting Active Directory schema. But administrators need to be cautious while using ADSIEdit for editing the AD Schema as any minor error with it would directly affect the health of the Domain Controller services. So, it is recommended to have an Ad-hoc backup in advance for the Domain Controller. Now, let us check out the steps involved in the complete removal of the failed Exchange Server from the schema.

    1. On the Exchange system, type msc in the Windows Run box and click OK.
    2. Next, right-click on the ADSIEDIT option and click Connect to.. option from the drop-down list.
    3. Enter Configuration against the Name section and then click OK.
    4. Next, expand these folders in sequence – Configuration>CN=Configuration>CN=Services
    5. Expand CN=Microsoft Exchange to check all Exchange Server installation configurations.
      Users can also navigate CN=Org for the same.
    6. Remove an Exchange Server from Active Directory Schema by expanding these folders in sequence – CN=Administrative Groups>CN=Exchange Administrative Group>CN=Servers>CN=Exchange. Then right-click on the Exchange Server (CN=Exchange) and select the Delete option to delete it completely from the AD Schema.
    7. The administrator’s next task would be to remove the Exchange Server from the Active Directory Users and Computers via Administrative Tools on the Exchange system.
      1. Next, expand the domain name>Microsoft Exchange Security Groups.
      2. Double-click on the Security Group to open it
      3. Switch to the Members tab, select the Exchange Server name and click the Remove option to remove it from the Active Directory Users and Computers.
      4. Finally, search and remove the Computer’s account using the Search feature in the Active Directory Users and Computers. Add Computers in the Find section, provide the server name against the Computer name section, and click the Find Now
      5. Once the Exchange Server name is retrieved, right-click on it and select the Delete option to delete it also completely.
    8. Hence, the native way to remove the failed Exchange Server from the Active Directory is completed.
