Syntax

Remove-AuthenticationPolicy
      [-Identity] <AuthPolicyIdParameter>

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

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 polices can't be applied.

Parameters

-AllowLegacyExchangeTokens

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 polices can't be applied.

Important:

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.
Legacy Exchange tokens will eventually be blocked by default in all cloud-based organizations. For more information, see Nested app authentication and Outlook legacy tokens deprecation FAQ.

-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.
