Description
You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't 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
Remove-AuthenticationPolicy -Identity "Engineering Group"
This example removes the authentication policy named "Engineering Group".
Example 2
Remove-AuthenticationPolicy -Identity "LegacyExchangeTokens" -AllowLegacyExchangeTokens
In Exchange Online, this example enables legacy Exchange tokens to be issued to Outlook add-ins. This switch applies to the entire organization. The Identity parameter is required, and its value must be set to "LegacyExchangeTokens". Specific authentication policies can't be applied.
Parameters
-AllowLegacyExchangeTokens
Applicable: Exchange Online, Exchange Online Protection
This parameter is available only in the cloud-based service.
The AllowLegacyExchangeTokens switch enables legacy Exchange tokens to be issued to Outlook add-ins for your organization. You don't need to specify a value with this switch.
Legacy Exchange tokens include Exchange user identity and callback tokens.
This switch applies to the entire organization. The Identity parameter is required, and its value must be set to "LegacyExchangeTokens". Specific authentication policies can't be applied.
Important:
- Legacy Exchange Online tokens will be turned off for all organizations from August 2025 through September 2025. Once turned off, you can't use the AllowLegacyExchangeTokens switch on the Set-AuthenticationPolicy cmdlet to turn on these tokens. You get the warning "Legacy Exchange Online tokens are disabled" when you run the command
Get-AuthenticationPolicy -AllowLegacyExchangeTokens. You can contact Microsoft Support to request an exception. For more information, see Nested app authentication and Outlook legacy tokens deprecation FAQ. - Apart from the Identity parameter, this switch disregards other authentication policy parameters used in the same command. We recommend running separate commands for other authentication policy changes.
- It might take up to 24 hours for the change to take effect across your entire organization.
- Legacy Exchange tokens issued to Outlook add-ins before token blocking was implemented in your organization will remain valid until they expire.

-Confirm
Applicable: Exchange Server 2019, Exchange Server SE, Exchange Online, Exchange Online Protection
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.
