What it does

If you enable this policy setting, you can remove or change the default value "home phone". It is recommended that you specify a MAPI property and a corresponding AD attribute. The MAPI property should always be specified, unless Outlook is not installed, in which case only the AD attribute needs to be specified. It must be entered in decimal format. If you know the MAPIHexadecimalPropertyTag, you should convert this to a decimal value. Any properties entered which are binary or list box, cannot be displayed and thus are ignored. For example, if you want to show the Assistant on the Contact Card, for MAPI, the PR_ASSISTANT hexadecimal property tag is 0x3A30001E. In decimal format, it is 976224286. You would enter: 976224286. To remove the value entirely you would enter null. Note that for Location and Calendar values on the default Contact Card, the defaults are not MAPI Properties or AD Attributes. Related policy settings: Replace AD attribute n, Turn On Contact Tab Calendar Line Move, Turn On Contact Tab Location Line Move. If you disable or do not configure this policy setting, the default value of "home phone" is shown.

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: L_HomeMAPIReplace
