How to Sync Google Calendar with Outlook (2026 Guide)

If you use Google Calendar for personal life and Outlook for work (or vice versa), you've probably double-booked yourself at least once. Keeping two calendars in sync shouldn't be this hard — but neither Google nor Microsoft makes it easy out of the box.

This guide covers every method for syncing Google Calendar with Outlook, from manual workarounds to fully automatic two-way sync.

TL;DR: The fastest way to get real-time, bidirectional sync between Google Calendar and Outlook is to use a dedicated sync tool like AllMyMeetings. It takes under two minutes to set up, and the free plan covers basic sync.

Why do you need to sync Google Calendar with Outlook?

Over 70% of knowledge workers use more than one calendar provider, according to a 2024 Reclaim.ai survey of 12,000 professionals. The most common combination is Google Calendar (used by over 500 million people) and Microsoft Outlook (used by over 400 million people).

Common reasons you might need both:

• Work uses Outlook, personal uses Google — the most common scenario
• Multiple jobs or freelance clients — each organization has its own calendar
• Transition between platforms — migrating from one provider to another
• Family coordination — shared Google calendars with a partner, Outlook at the office

Without sync, you're left manually checking two calendars before booking anything — or worse, discovering conflicts after it's too late.

Method 1: Subscribe to Google Calendar in Outlook (read-only)

You can import a read-only copy of your Google Calendar into Outlook using an ICS link. This approach is free and requires no third-party tools.

This method shows your Google events inside Outlook, but changes only flow one way and updates can take 24-48 hours to appear.

Step 1: Get your Google Calendar's ICS link

1. Open Google Calendar in a browser
2. Click the three dots next to the calendar you want to share
3. Select Settings and sharing
4. Scroll to Integrate calendar
5. Copy the Secret address in iCal format URL

Step 2: Add the ICS link in Outlook

1. Open Outlook and go to the Calendar view
2. Click Add calendar → Subscribe from web
3. Paste the ICS URL
4. Name the calendar and click Import

Limitations of this method

• One-way only — events created in Outlook won't appear in Google
• Delayed updates — changes can take 12-48 hours to sync
• Read-only — you can't edit Google events from Outlook
• No free/busy blocking — Outlook won't treat these events as "busy" time for scheduling

Method 2: Subscribe to Outlook Calendar in Google (read-only)

The reverse approach works similarly. Export your Outlook calendar as an ICS link and subscribe in Google Calendar.

This method also provides one-way, read-only visibility with significant delays in update propagation.

Step 1: Get your Outlook calendar's ICS link

1. Open Outlook on the web
2. Click the gear icon → View all Outlook settings
3. Go to Calendar → Shared calendars
4. Under Publish a calendar, select your calendar and permission level
5. Click Publish and copy the ICS link

Step 2: Subscribe in Google Calendar

1. Open Google Calendar
2. Click the + next to "Other calendars"
3. Select From URL
4. Paste the ICS link and click Add calendar

Limitations

The same constraints apply: one-way sync, significant delays, and no ability to edit events across platforms. If someone books over an Outlook meeting in your Google Calendar, you won't know until it's too late.

Method 3: Automatic two-way sync with AllMyMeetings

For real-time, bidirectional sync that actually prevents double-booking, you need a dedicated sync tool. AllMyMeetings connects directly to both Google and Outlook APIs using OAuth, enabling changes to propagate in seconds via webhooks.

Dedicated sync tools create "blocker" events that mark your time as busy across both calendars, so scheduling tools and colleagues see your real availability everywhere.

Step 1: Create a free AllMyMeetings account

Go to allmymeetings.com and sign up. No credit card required for the free plan.

Step 2: Connect your Google account

Click Add Calendar Account, select Google, and authorize access. AllMyMeetings uses OAuth 2.0, so it never sees your password.

Step 3: Connect your Outlook account

Click Add Calendar Account again, select Microsoft, and authorize. Same secure OAuth flow.

Step 4: Create a sync pair

Select your Google calendar as the source and Outlook calendar as the destination (or vice versa). Choose your sync settings:

• Direction: One-way or bidirectional
• Sync mode: Full details, free/busy only, or private
• Title suffix: Optionally tag synced events (e.g., "[Personal]")

Click save, and your calendars begin syncing immediately. Changes propagate in under 5 seconds for both Google and Outlook, thanks to real-time webhook integration.

Why this method is better

Which method should you choose?

For casual visibility into another calendar where timeliness doesn't matter, ICS subscription works fine. It's free and requires no additional tools.

For anyone who schedules meetings, manages clients, or simply can't afford to double-book, real-time bidirectional sync is worth the upgrade. The free plan on AllMyMeetings covers one sync pair, which is all you need for a basic Google-Outlook setup.

If you need more than two calendars synced — say, a work Outlook, personal Google, and shared family Google calendar — the Pro plan at $5/month covers up to 4 accounts and 6 sync pairs.

Frequently asked questions

Can I sync specific calendars rather than my entire account?

Yes. When you connect a Google or Outlook account, AllMyMeetings discovers all calendars within that account. You choose exactly which calendars to include in each sync pair.

Will synced events show the full meeting details?

That depends on the sync mode you choose. "Full details" copies everything. "Free/busy" creates generic "Busy" blocks that hide specifics. "Private" creates private events. Most people use free/busy mode for cross-account sync to keep work and personal life separate.

Does sync work with shared/delegated calendars?

Yes. AllMyMeetings can sync any calendar that your account has access to, including shared calendars within a Google Workspace or Microsoft 365 organization.

Is there a limit to how far back events sync?

The sync window covers events within a configurable range, typically 30 days in the past and 60 days in the future. This is adjustable per calendar account.
