This example removes the ExchangeMail OnPremisesOrganization object in an Office 365 tenant.

Remove-OnPremisesOrganization -Identity ExchangeMail

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 infrastructure and PowerShell 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 specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.

  • Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax: -Confirm:$false.

  • Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.




The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
