Dont waste your time trying to sync the N900 with Anything, And dont listen to people here telling you to use IMAP, no good admin would leave the IMAP port open on a server, well certainly no good nix admin at any rate, and pop is *almost* useless. Nokia falsely advertised exchange sync/mislead people as to the N900's REAL Syncing capabilities. Carrier Pigeon would be a better bet/faster than waiting for Nokia to implement this most basic of features.
