How To Sync Outlook Calendar with Google Calendar

Many professionals rely on Microsoft Outlook for work while using Google Calendar for personal scheduling. The problem is that these two platforms don't talk to each other — your Outlook colleagues can't see your personal commitments, and your personal calendar has no idea about your work meetings.

Don't Double Book Me connects your Outlook and Google calendars so that your availability stays accurate everywhere. When a meeting lands on your Outlook calendar, a corresponding busy block appears on Google Calendar — and vice versa.

Why Sync Outlook with Google Calendar?

When your work runs on Microsoft 365 and your personal life runs on Google, you end up managing two separate schedules. Without a sync, accepting a personal appointment during a work meeting is easy to do by accident. You might also block time on your work calendar manually — a tedious process that falls out of date the moment things change.

Automatic syncing eliminates the manual overhead. Your busy times are reflected on both calendars within seconds, and you control exactly how much detail is shared. Work colleagues see "Busy" on your Outlook calendar; they don't need to know it's a dentist appointment.

Start Syncing Outlook with Google Calendar

Don't Double Book Me makes it simple to keep your Outlook and Google calendars in sync. Here's how to get started:

  1. Connect your Microsoft Outlook Account with Don't Double Book Me.

    You will be prompted to give Don't Double Book Me the proper permissions to access your Outlook calendar. We need read & write access to your calendar to sync your events.

  2. Connect your Google Account.

    Add your Google account so Don't Double Book Me can read and write events on your Google Calendar.

  3. Select the calendars you want to sync.

    Pick your Outlook calendar as the source and your Google Calendar as the destination (or the other way around). You can create as many syncs as you need.

  4. Configure your sync preferences.

    Choose event visibility (show as Busy, Private, or match the original), set working hours, enable rounded event times, and decide whether to sync all-day events or invitations.

  5. Your calendars are now syncing in real-time. 🎉

    Events sync automatically via webhooks — no manual refresh needed. Changes, cancellations, and new bookings propagate within seconds.

Start with a 1-week free trial (no credit card required), then enjoy seamless cross-provider syncing for just $20/year. That's less than two months of most competing services.

What Is Don't Double Book Me?

Don't Double Book Me reserves time between your Outlook and Google calendars, ensuring your schedule is conflict-free without sharing your sensitive event details across providers.

  • Cross-Provider Sync. Sync events marked as Busy between Microsoft Outlook and Google Calendar in real-time. Your availability updates as soon as you're booked on either platform, ensuring no overlaps.
  • Privacy Controls. Choose how events appear on the other calendar — show as Busy with no details, keep the original visibility, or mark as Private. Your personal appointments stay personal.
  • Respect Your Working Hours. Set specific hours during which you want events to be synced. Events starting before or ending after your working hours will be adjusted to match.
  • Rounded Event Times. Automatically round the start and end times of your events to the nearest 15 or 30 minutes. This helps in creating a cleaner, more organized calendar view.
