Set-AvailabilityConfig

 

Applies to: Exchange Online, Exchange Server 2016

This cmdlet is available in on-premises Exchange Server 2016 and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.

Use the Set-AvailabilityConfig cmdlet to set the access level for free/busy information.

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

Set-AvailabilityConfig [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-OrgWideAccount <SecurityPrincipalIdParameter>] [-PerUserAccount <SecurityPrincipalIdParameter>] [-WhatIf [<SwitchParameter>]]

This example is useful with a trusted cross-forest Availability service. If the remote forest is trusted, and a per-user free/busy proxy account or group in the remote forest is configured to use the service account, the configuration is added to the current forest to authorize the Microsoft ActiveSync request from the remote forest.

Set-AvailabilityConfig -PerUserAccount <domain name of servers group in remote forest>

This example is useful if the remote forest isn't trusted. Because this account is used for a cross-forest free/busy proxy account or group, minimize security vulnerabilities by using the credentials of a user who doesn't have an Exchange mailbox. When you're prompted, type the user name and password.

Set-AvailabilityConfig -OrgWideAccount <ExampleCredentials>

The Set-AvailabilityConfig cmdlet defines two accounts or security groups: a per-user free/busy proxy account or group, and an organization-wide free/busy proxy account or group. These accounts and groups are trusted by all availability services in the current organization for availability proxy requests.

For cross-forest availability services to retrieve free/busy information in the current forest, they must be using one of the specified accounts, belong to one of the specified security groups, or have a user name and password for one of the specified accounts or security groups.

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 "Availability service configuration settings" entry in the Clients and mobile devices permissions topic.

 

Parameter Required Type Description

Confirm

Optional

System.Management.Automation.SwitchParameter

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.

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

This parameter is available only in on-premises Exchange 2016.

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.

OrgWideAccount

Optional

Microsoft.Exchange.Configuration.Tasks.SecurityPrincipalIdParameter

The OrgWideAccount parameter specifies an account or security group that has permission to issue proxy Availability service requests on an organization-wide basis.

PerUserAccount

Optional

Microsoft.Exchange.Configuration.Tasks.SecurityPrincipalIdParameter

This parameter is available only in on-premises Exchange 2016.

The PerUserAccount parameter specifies an account or security group that has permission to issue proxy Availability service requests on a per-user basis.

WhatIf

Optional

System.Management.Automation.SwitchParameter

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.

Identity

Optional

Microsoft.Exchange.Configuration.Tasks.OrganizationIdParameter

The Identity parameter specifies the OrganizationID.
