There is a built-in synchronisation feature (see Tools->Synchronise...). However, it's very complicated and involves several steps using identical interfaces on both clients so it's very difficult not to lose your place and screw the whole thing up. What's worse, if you try to use Voyager when travelling (presumably the whole point of it) across timezones, the timestamps on emails will be different, so synching will leave you with duplicates of every message in The Bat!, and the 'Delete Duplicates' function won't work. The only solution is to find and delete these duplicates manually, which is great fun if you have thousands of messages Ritlabs really need to work on a one-click synch that works properly, if Voyager is to be of any real use.


Actually, The Bat's mail base doesn't need to be encrypted to work with Voyager. However, as Voyager is meant to be run from a USB key, only its local mail base is encrypted and requires a password.
