Local, on-device sync
The app runs on your Mac instead of as a cloud service, so calendar data stays on-device while syncs are performed directly between your Outlook client and Google.
Outlook Google Calendar Sync for Mac
Outlook Google Calendar Sync for Mac mirrors Outlook events to Google Calendar on your Mac—no cloud intermediary or Microsoft admin approval needed.
Outlook-to-Google calendar sync for Mac
Outlook Google Calendar Sync for Mac is a macOS app that mirrors events from Outlook to Google Calendar while running entirely on your Mac. The product is positioned for people who want their calendars kept in sync without using a cloud intermediary or waiting for Microsoft admin approval.
The site emphasizes a simple one-way workflow: connect your Outlook and Google accounts, pair the calendars you want to sync, and let the app run in the background. It also highlights support for multiple sync jobs, menu bar access, and a 30-day free trial with no credit card required.
Everything you need, nothing you don't
Multiple sync jobs
Set up multiple independent jobs, each connecting one Outlook calendar to one Google calendar, so different calendar pairs can be handled separately.
Background syncing with menu bar access
Background sync keeps calendars matched automatically and the site says jobs can sync as often as every minute, with a menu bar presence for on-demand checks.
Private event mirroring
Attendees are masked when events are mirrored, which helps prevent invitations from being sent when a calendar entry is copied across.
Smart de-duping
Recurring events and exceptions are matched carefully to avoid duplicates and reduce drift between calendars.
Selectable sync window
You can limit syncs to a chosen time window, such as a few days back and weeks ahead, instead of copying every event in the calendar.
Common ways to use it
Work-to-personal calendar mirroring
Keep a personal Google Calendar updated from a work Outlook calendar so your day stays visible outside your office account.
Multiple calendar pairs
Maintain separate sync jobs for different calendars, such as work, team, or travel, without mixing them into one shared flow.
Self-managed Mac setup
Run a local sync tool on a Mac when you want to avoid cloud-based calendar services and the Microsoft admin approval flow.
Selective date-window syncing
Limit syncing to a smaller time range when you only need recent events and upcoming entries in Google Calendar.

No. The current release includes a 30-day trial with no payment information required, and the site says paid plans are coming soon.
Will mirrored events send duplicate invites to coworkers?
