 > - Resources stored in Microsoft Entra ID (such as users and groups) support "sync from now" scenarios. This allows you to skip steps 1 and 2 (if you're not interested in retrieving the full state of the resource) and ask for the latest `@odata.deltaLink` instead. Append `$deltatoken=latest` to the `delta` function and the response will contain a `@odata.deltaLink` and no resource data. Resources in OneDrive and SharePoint also support this feature but require `token=latest` instead.
