Did you manage to enable the sync of flag changes for messages already synced? This issue seems to be unsolved.

At least for me, the consequences of switching off the caches seem to be negligible as most users use activesync and desktop clients.

There is still one remaining issue though: If a message has already been loaded on the Activesync device, changes to messages in RoundCube to not appear on the Activesync device.
