What it does

XFA is a legacy technology that's deprecated by its original creators. It's not an ISO standard and as such, it doesn't align with the modern web architecture. Continued use poses potential risks and vulnerabilities. For more information, see 'ViewXFAPDFInIEModeAllowedOrigins' (View XFA-based PDF files using IE Mode for allowed file origin.). If you enable this policy, you can configure the list of base64 encoded SHA256 file hashes for which XFA PDF files automatically open in Microsoft Edge using IE Mode. If you disable or don't configure this policy, XFA PDFs won't be considered for opening via IE mode except the files from file origin mentioned in Policy 'ViewXFAPDFInIEModeAllowedOrigins' For more information, see - [Get-FileHash](https://go.microsoft.com/fwlink/?linkid=2294823), [Dot Net Convert API](https://go.microsoft.com/fwlink/?linkid=2294913).

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
The generated payload is incomplete because one or more ADMX element values were not supplied: ViewXFAPDFInIEModeAllowedFileHashDesc
