Our verdict on OggSync
OggSync is a Windows desktop application for individuals, professionals, and small teams managing calendars across Microsoft Outlook and Google. Its core job is two-way synchronization between Outlook and Google Calendar, with support for recurring events, multiple calendars, configurable sync direction, and Google Workspace accounts. It is a focused synchronization utility rather than a broad calendar app, making it a practical fit for Outlook users who need their Google calendars to stay aligned.
The plan structure keeps the basic workflow accessible. The Free plan includes two-way calendar sync, support for one calendar, manual synchronization, and recurring events. Pro costs $29 per device per year and adds multiple calendars, automatic scheduled sync, Google Contacts and Google Tasks synchronization, and priority support. For someone managing one calendar and comfortable starting sync manually, Free covers the essential exchange. The annual per-device price makes Pro more relevant when scheduled updates, additional calendars, or Outlook access to Google contacts and tasks justify the cost.
OggSync’s depth is in synchronization control. It supports recurring-event exceptions, configurable sync direction, and conflict-resolution rules where the most recent change, Google, or Outlook can win. Local synchronization through Google’s official Calendar API also suits users who prefer the application to communicate directly with Google rather than route calendar data through intermediary servers. The trade-off is a narrow platform focus: OggSync runs on Windows, supports Microsoft Outlook 2010 or later, and has no mobile apps. Choose it for detailed Outlook-Google coordination on Windows; choose an alternative if mobile access or broader platform coverage is central.
