 **Important**:
 
-- Currently, the AllowLegacyExchangeTokens switch only specifies whether legacy Exchange tokens are allowed in your organization. For now, disregard the empty Allowed and Blocked arrays returned by the switch.
-- Legacy Exchange tokens will eventually be blocked by default in all cloud-based organizations.

+- As of February 24, 2025, the AllowLegacyExchangeTokens switch specifies any add-in that requested an Exchange token.
+- The AllowLegacyExchangeTokens switch returns `Not Set` if tokens haven't been explicitly allowed or blocked in your organization using the _AllowLegacyExchangeTokens_ or _BlockLegacyExchangeTokens_ parameters on the **Set-AuthenticationPolicy** cmdlet.
