Updating "SingleValueExtendeProperties" of Draft item through Graph causing duplicate draft copies

sumitra dash 0 Reputation points

I am trying to update the draft item through my outlook add-in. Add-in sends a patch request to graph api to update the "SingleValueExtendedProperties" . However once I send the draft item, I am seeing the below message for the item in sent items folder "This is the most recent version, but you made changes to another copy. Click here to see the other versions". Once I open and send it, it sends the actual copy that got updated through graph. Anyone encountered this issue? Is there a proper way to achieve this workflow? All I want is to be able to update the email in compose mode with a property.
