Question

Graph ListItem Delta API does not return "lastModifiedBy" property

Answer 1

Hi @Kevin Zhu

Thank you for posting your question in the Microsoft Q&A forum. 

The lastModifiedBy property is not returned by the ListItem Delta API, and this is expected behavior. The delta API is optimized for tracking changes, so it only includes properties that can change and are tracked by the delta token. It is not intended to provide the full set of item metadata. 

For retrieving lastModifiedBy or other static metadata, you’ll need to query the item directly outside of the delta call. 

You can read more at listItem: delta - Microsoft Graph v1.0 | Microsoft Learn. 

I hope this helps clarify the behavior
