Eltima Software (http://mac.eltima.com/) says SyncMate 3 now fully supports data synchronization with Outlook 2011. The app requires Mac OS X 10.5 or higher. It costs US$39.95 for a personal license (for use with two Macs), though version 3 is a free update for registered users.

SyncMate enables anyone to synchronize Macs with Windows Mobile and Android devices, Nokia S40 phones, Windows PCs, other Mac computers, Google accounts, Sony PlayStation Portable, USB flash drives and allows backing up Mac data online. Synchronization of Outlook 2011 supports calendar, contacts, notes and tasks with their analogues in supported devices.

While it was possible to sync Outlook 2011 contacts in previous versions, calendar, notes and tasks were not supported before. (You’ll need to install Service Pack 1 for Microsoft Office 2011 for Mac and enable sync service options in Outlook preferences).

SyncMate is a sync tool for Mac OS X that syncs data in Mac with multiple devices within one app. Among supported devices are Windows Mobile and Android devices, Nokia S40 phones, Mac and Windows computers, USB flash drives, Sony PSP, Google accounts. SyncMate also offers free online storage for data backup.
