Detailed Description

Removing an OnPremisesOrganization object should only be used in circumstances where the hybrid deployment state is corrupt and under the direction and supervision of Microsoft Customer Service and Support. After removing the OnPremisesOrganization object, any related hybrid deployment configured with this object won't be functional and will need to be re-created and reconfigured.

You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Hybrid deployment configuration" entry in the Exchange and Shell Infrastructure Permissions topic.


Parameter Required Type Description




The Identity parameter specifies the identity of the on-premises organization object. You can use the following values:

  • Canonical name

  • GUID

  • Name




The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch.
