OggSync

Sync Outlook with Google Calendar

OggSync is a Windows desktop application that synchronizes Microsoft Outlook with Google Calendar. It provides two-way synchronization for calendars, contacts, and tasks, connecting directly to Google's API without intermediary servers that store user data. The tool addresses the need to keep Outlook and Google calendars aligned, including recurring events with exceptions, without manual copying or reliance on third-party sync services.

Key capabilities include two-way calendar synchronization, support for multiple Google calendars in a unified Outlook view, recurring event handling, contacts and tasks sync, and automatic scheduled or manual synchronization. It supports Google Workspace business domains and works with Outlook 2010 and later on Windows. OggSync is available in a Free edition offering two-way calendar sync for a single calendar with manual sync and recurring events, and a Pro edition that adds multiple calendars, automatic scheduled sync, contacts and tasks sync, and priority support. The Pro edition is offered on an annual subscription basis.
