OggSync

What OggSync is
OggSync synchronizes Outlook with Google Calendar and supports two-way syncing for calendars, contacts, and tasks. Recurring events are supported, including exceptions within a recurring series. The default synchronization window covers events within 365 days, and this range can be customized. OggSync works with personal Google accounts and Google Workspace business accounts, although an organization administrator may need to approve access. Calendar data is stated to move directly between your computer and Google’s servers rather than through OggSync’s servers. The Google authorization token is stored locally, and OggSync says it requests only permissions needed for calendar synchronization, without accessing email or other Google services. The Free plan costs nothing and provides one calendar with manual two-way sync. Pro costs $29 a year, billed at $29/year, adding multiple calendars, scheduled sync, contacts and tasks, and priority support.
