Apparently no one directly supports Entourage 2008 due to the fact that it now syncs exclusively through Sync Services, but based on what I've seen Missing Sync simply does what I've been doing through PocketMac (i.e., using iCal to transfer data between the BB and Entourage.)
The entourage help blog (
Warning: Syncing with Entourage 2008 (The Entourage Help Blog)) describes the same process I've been using, as do a number of posts on this forum, but I can't figure out how to deal with the problem of the different calendars in iCal. Has anyone had any luck using this method, or with Missing Sync doing it for them?
