Applies to: Exchange Server 2016

This cmdlet is available only in on-premises Exchange Server 2016.

Use the Move-OfflineAddressBook cmdlet to designate a new server responsible for generating the offline address book (OAB).

For information about the parameter sets in the Syntax section below, see Syntax.

Move-OfflineAddressBook -Identity <OfflineAddressBookIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-Server <ServerIdParameter>] [-WhatIf [<SwitchParameter>]]

This example moves OAB generation to the server Server1.

Move-OfflineAddressBook -Identity "My OAB" -Server "Server1"

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 "Offline address books" entry in the Email address and address book permissions topic.

By default in Exchange Online, the Address List role isn’t assigned to any role groups. To use any cmdlets that require the Address List role, you need to add the role to a role group. For details, see the “Add a role to a role assignment policy” section of Manage role assignment policies.


Parameter Required Type Description




The Identity parameter specifies the GUID, distinguished name (DN), or OAB name that represents a specific OAB. You can also include the path by using the format Server\OfflineAddressBookName.

You can omit the parameter label so that only the OAB name or GUID is supplied.




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 DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.




The Server parameter specifies the Mailbox server on which to perform the selected operation.




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.

To see the input types that this cmdlet accepts, see Cmdlet Input and Output Types. If the Input Type field for a cmdlet is blank, the cmdlet doesn’t accept input data.

To see the return types, which are also known as output types, that this cmdlet accepts, see Cmdlet Input and Output Types. If the Output Type field is blank, the cmdlet doesn’t return data.
