Remarks​

To create a schema extension, you have to specify a unique ID for the schema extension. You can assign a value in one of two ways:

  • concatenate the name of one of your verified domains with a name for the schema extension to form a unique string in this format, {domainName}_{schemaName}, eg. contoso_mySchema.

    NOTE: Only verified domains under the following top-level domains are supported: .com, .net, .gov, .edu or .org.

  • Provide a schema name, and let Microsoft Graph use that schema name to complete the id assignment in this format: ext{8-random-alphanumeric-chars}_{schema-name}, eg. extkvbmkofy_mySchema.

The schema extension ID cannot be changed after creation.

The schema extension owner is the ID of the Microsoft Entra application that is the owner of the schema extension. Once set, this property is read-only and cannot be changed.

The target types are the set of Microsoft Graph resource types (that support schema extensions) that this schema extension definition can be applied to. This option is specified as a comma-separated list

Escaping JSON in PowerShell

When using the --properties option it's possible to enter a JSON string. In PowerShell 5 to 7.2 specific escaping rules apply due to an issue. Remember that you can also use file tokens instead.
