It definitely works. Updates just as fast as I get email, which is better than the owa sync bb offers.

They seem to be updating it a lot recently, so I've had to get the beta for each update, because it stopped grabbing my email shortly after each beta announcement. Upgrading to the newest beta version seemed to fix it.
Also only seems to update the calendar 2 weeks in advance. But all in all a fine alternative to no access at all or the owa blackberry sync thing.
