'End appointments and meetings early' feature now broken in Office Cloud Policy Service

This policy setting allows you to shorten the default duration of appointments and meetings by a specified number of minutes. If you enable this policy setting, you can choose between the following options: End Early, Start Late, None. If you select End Early, meetings and appointments will end early by the specified number of minutes. If you select Start Late, meetings and appointments will start late by the specified number of minutes. If you select None, the default meeting duration will not be shortened. In all cases, the settings for this feature will be disabled in the Outlook Options dialog. If you don’t configure this policy setting, users can modify these settings by going to File > Options > Calendar. Note: This policy setting only applies to subscription versions of Office, such as Microsoft 365 Apps for enterprise.

This policy setting allows you to specify how many minutes to reduce the end time of a short appointment or meeting by when a user creates an appointment or meeting. A short appointment or meeting is one that lasts for less than one hour. If you enable this policy setting, you specify the number of minutes to reduce the end time of a short appointment or meeting by when a user creates an appointment or meeting. The user can’t change this value by going to File > Options > Calendar. Note: You should also enable the “End appointments and meetings early” policy setting. If you disable or don’t configure this policy setting, the default value of 5 minutes is used or whatever the user specifies by going to File > Options > Calendar. Note: This policy setting only applies to subscription versions of Office, such as Microsoft 365 Apps for enterprise.

Microsoft just released an updated set of AMDX templates: https://www.microsoft.com/en-us/download/details.aspx?id=49030. This should resolve the issue, as the GPO policy now uses the updated values.

Sadly no.. Have tried reg keys and everything, but no luck..
Still havent seen an officel acknowledgement from Microsoft on this issue

But what are you packaging in the win32 app?
Powershell script, Bat or something else?

PowerShell wont work as it is user registry keys.
Windows app (win32 ) : Apps-windows-select app type
