Set-AvailabilityConfig

This parameter is available only in the cloud-based service.

The AllowedTenantIds parameter specifies the tenant ID values of Microsoft 365 organization that you want to share free/busy information with (for example, d6b0a40e-029b-43f2-9852-f3724f68ead9). You can specify multiple values separated by commas. A maximum of 25 values are allowed.

To replace all existing tenant IDs with the values you specify, use the following syntax: "TenantID1","TenantID2",..."TenantID25".

To add or remove tenant IDs without affecting other existing values, use the following syntax: @{Add="TenantID1","TenantID2",...; Remove="TenantID3","TenantID4",...}.

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.

This parameter is available only in on-premises Exchange.

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.

This parameter is functional only in on-premises Exchange.

The OrgWideAccount parameter specifies who has permission to issue proxy Availability service requests on an organization-wide basis. You can specify the following types of users or groups (security principals) for this parameter:

• Mailbox users
• Mail users
• Security groups

You can use any value that uniquely identifies the user or group. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Domain\Username
• Email address
• GUID
• LegacyExchangeDN
• SamAccountName
• User ID or user principal name (UPN)

This parameter is available only in on-premises Exchange.

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

You can use any value that uniquely identifies the user or group. For example:

• Name
• Alias
• Distinguished name (DN)
• Canonical DN
• Domain\Username
• Email address
• GUID
• LegacyExchangeDN
• SamAccountName
• User ID or user principal name (UPN)

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.
