Appinv.aspx page can't be added to iframe (KB5005546) - Microsoft Support [MS]


When you try to open the Appinv.aspx page in an iframe, the page isn't successfully displayed. When this issue occurs, the request response headers include an "X-FRAME-OPTIONS: DENY" message.


To help maintain security, the Appinv.aspx page is prevented from being displayed in an iframe.


To fix this issue, install one of the following updates:

To display the Appinv.aspx page in an iframe in trusted domains, the farm administrator can add the trusted domains to the AllowIframeAppAuthorizePageDomains list in the farm by running the following commands:

add-pssnapin *
$f.AddGenericAllowedListValue("AllowIframeAppAuthorizePageDomains","<enable domain name>")


  • You can add one trusted domain to the AllowIframeAppAuthorizePageDomains list by using the commands every time. Additionally, you can add a wildcard domain, such as *, to AllowIframeAppAuthorizePageDomains.

  • If you receive the following error message, use AllowIframeAppAuthorizePageDomains2 instead of AllowIframeAppAuthorizePageDomains when you call the AddGenericAllowedListValue method:

    "AllowIframeAppAuthorizePageDomains" already exists under the parent Microsoft.SharePoint.Administration.SPFarm named…

    Additionally, make sure that you have the Microsoft SharePoint Server March 2022 updates installed.

Added a note to the "Resolution" section to provide a fix if the AllowIframeAppAuthorizePageDomains setting cannot be applied.
