Error moving emails between folders using Microsoft Graph

Hi

I am getting the issue below when moving an email between subfolders of an inbox when a follow up flag and/or completed date is set on the email.

'Operation failed.: Unexpected character encountered while parsing value: {. Path ‘flag.dueDateTime’, line 1, position 2742

Extract of email odata, starting at position 2696, position 2742 should be highlighted in bold.
,“flag”:{“flagStatus”:“flagged”,“dueDateTime”:{“dateTime”:“2026-05-20T23:00:00.0000000”,“timeZone”:“UTC”},“startDateTime”:{“dateTime”:“2026-05-20T23:00:00.0000000”,“timeZone”:“UTC”}}}

When the follow up flag is removed the email can be moved between folders.
I am using Email.Net 26.4 and Micrsoft.Graph to connect Exchange 365

Regards
Ian
