Resolution of Bug 10545 - support create/edit/import/migrate/sync outlook notes means that Outlook Notes sync is finally coming to Zimbra (apparently in 8.0).
However, I just had a user visit me and ask if Zimbra can sync his Outlook Notes with his iPhone. I realized that bug 10545 won't really accomplish this in an ideal fashion. Sure, he'll be able to use the mobile web interface (once Bug 59075 - Document error on Android is fixed), but I think it would be much more desirable if ActiveSync or IMAP could be leveraged to bring Outlook Notes into the native iOS Notes app. It turns out that this is already doable for MobileMe and IMAP with Mac Mail.
If you'd like to see this feature, please vote for Bug 66566 - RFE: support Notes syncing for iOS 4+
