Set-OfflineAddressBook

This cmdlet is available in on-premises Exchange and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.

Use the Set-OfflineAddressBook cmdlet to modify offline address book (OAB) settings.

In Exchange Online, this cmdlet is available only in the Address Lists role, and by default, the role isn't assigned to any role groups. To use this cmdlet, you need to add the Address Lists role to a role group (for example, to the Organization Management role group). For more information, see Add a role to a role group.

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

Description

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.

Examples

Example 1

Set-OfflineAddressBook -Identity "Default Offline Address Book" -VirtualDirectories $null -GlobalWebDistributionEnabled $true

This example configures the OAB named Default Offline Address Book to be available for download requests from all OAB virtual directories in the organization.

Example 2

Set-OfflineAddressBook -Identity "\Default Offline Address Book" -GeneratingMailbox OABGen2

This example changes the organization mailbox that's responsible for generating the OAB.

Parameters

-AddressLists

The AddressLists parameter specifies the address lists or global address lists that are included in the OAB. You can use any value that uniquely identifies the address list. For example:

  • Name
  • Distinguished name (DN)
  • GUID

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

You can find the identify values of address lists and global address lists by using the Get-AddressList and Get-GlobalAddressList cmdlets.

Type:AddressBookBaseIdParameter[]
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

-ApplyMandatoryProperties

The ApplyMandatoryProperties switch specifies whether to update the mandatory properties of a legacy OAB. You don't need to specify a value with this switch.

This switch was used in coexistence environments when an OAB was migrated from Exchange 2003.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

-ConfiguredAttributes

The ConfiguredAttributes parameter specifies the recipient MAPI properties that are available in the OAB. This parameter uses the syntax: "Name1,Type1","Name2,Type2",..."NameN,TypeN" where Name is the name of the MAPI property (for example, MobileTelephoneNumber), and Type is the value ANR (ambiguous name resolution), Value, or Indicator.

To reset this parameter back to the default values, use the UseDefaultAttributes switch.

Type:MultiValuedProperty
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

-Confirm

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.

-GeneratingMailbox

This parameter is available only in on-premises Exchange.

The GeneratingMailbox parameter specifies the arbitration mailbox where the OAB is generated. Specifically, the arbitration mailbox must contain the OrganizationCapabilityOABGen value for the PersistedCapability property. An arbitration mailbox with this capability is also known as an organization mailbox. You can use any value that uniquely identifies the mailbox. For example:

  • Name
  • Alias
  • Distinguished name (DN)
  • Canonical DN
  • Domain\Username
  • Email address
  • GUID

The Schedule parameter specifies the interval for generating the OAB in Exchange 2010 or earlier.

The syntax for this parameter is: StartDay.Hour:Minute [AM | PM]-EndDay.Hour:Minute [AM | PM].

You can use the following values for days:

  • Full name of the day.
  • Abbreviated name of the day.
  • Integer from 0 through 6, where 0 = Sunday.

You can enter the time in 24 hour format and omit the AM/PM value. If you enter the time in 12 time hour format, include a space between the time and the AM/PM value.

You can mix and match date/time formats.

The start time and end time must be at least 15 minutes apart. Minutes are rounded down to 0, 15, 30, or 45.

Here are some examples:

  • "Sun.11:30 PM-Mon.1:30 AM"
  • "6.22:00-6.22:15" (Run from Saturday at 10:00 PM until Saturday at 10:15 PM.)

-ShadowMailboxDistributionEnabled

This parameter is available only in on-premises Exchange.

The ShadowMailboxDistributionEnabled parameter specifies whether a read only copy of the OAB (also known as a shadow copy) is distributed to all other OAB generation mailboxes (also known as organization mailboxes). This allows additional Mailbox servers to be endpoints for requests to download the OAB, which can help prevent users from downloading the OAB across slow WAN links. Valid values are:

  • $true: The OAB is distributed to all other organization mailboxes.
  • $false: The OAB is isn't distributed to other organization mailboxes. This is the default value.

The value of this parameter is only meaningful if you have multiple organization mailboxes, and is only beneficial in Exchange organizations that have multiple Active Directory sites.

Type:Boolean
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019

-UpgradeFromE14

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2016, Exchange Server 2019, Exchange Online

-UseDefaultAttributes

The UseDefaultAttributes switch specifies whether to revert the recipient MAPI properties that are available in the OAB to the default list. You don't need to specify a value with this switch.

You can use this switch to undo changes that you've made to the default list by using the ConfiguredAttributes parameter.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

-Versions

The Versions parameter specifies the OAB versions that are generated for client download. Valid values are:

  • Version2 (requires public folder distribution)

Type:MultiValuedProperty
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

-VirtualDirectories

This parameter is available only in on-premises Exchange.

The VirtualDirectories parameter specifies the OAB virtual directories that accept requests to download the OAB. These locations are advertised in the Autodiscover service.

You can use any value that uniquely identifies the virtual directory. For example:

  • Name or Server\Name
  • Distinguished name (DN)
  • GUID

The Name value uses the syntax "VirtualDirectoryName (WebsiteName)" from the properties of the virtual directory. You can specify the wildcard character (*) instead of the default website by using the syntax VirtualDirectoryName*.

The default value of this parameter is the Client Access services (frontend) and backend OAB virtual directories on the Mailbox server that holds the OAB generation mailbox (the GeneratingMailbox parameter or SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c}) when you created the OAB (for example, Mailbox01\OAB (Default Web Site),Mailbox01\OAB (Exchange Back End).

To use this parameter, the value of the GlobalWebDistributionEnabled parameter must be $false.

In Exchange 2013 CU7 or later, we recommend that you set this parameter to $null, and then set the GlobalWebDistributionEnabled parameter to $true, because the Client Access services on any Mailbox server can proxy incoming OAB download requests to the correct location.

Type:VirtualDirectoryIdParameter[]
