Dear experts,
I'm using CSOM to upload files to Sharepoint Online. When I do so, I can set the Created and Modified datetimes to anything I like.
When using the web-based view in Sharepoint Online, the Created and Modified datetime I set, displays as expected.
However, when using the 'Explorer View' or mapping through WebDav, the Modifieddate of the file equals the upload date+time in Sharepoint Online, but the Created date does respect the datetime I set.
Which property of my list item is the Modified time that displays through WebDav, and how do I modify it using CSOM so my WebDav client also sees the customized Modified Date?
