Reply and Forward marks do not sync from server to device.
Apple devices do not support the syncing of Reply and Forward marks. These marks are considered local to the device or local to the server, and never synchronized. However, if you reply or forward a mail message on the device, the corresponding message in the server mail database will reflect the reply or forward mark.
Viele Grüße
