Oh, and it needs to sync Contacts, Calendar, Tasks and Memos. Ideally by syncing thru the native PIM (Outlook <> Berry PIM <> 3rd party PIM <>) though this isn't absolutely mandatory. Not interested in a cloud-based solution.
I've, coincidentally, been on the hunt for something for the past 24 hours as well. I really need something that will sync Outlook on my Mac without using BES. (BES only lets you have 1 email address- I have 10 and 5 are Gmail.)
There's Synacmatic & Funambol, but their websites are so incomplete. I don't think they work with Outlook for Mac, but with the native Apple Calendar and Contacts app.
