The fastest way: sync through your Microsoft account

The simplest path is to connect your Google Calendar through your Microsoft account settings, which lets Outlook pull in your Google events without leaving Outlook. You do not need to install anything extra or switch between apps. Open Outlook on your computer or phone, go to Settings, then Calendar, then Add calendar. Choose Subscribe from the internet, paste your Google Calendar's public address (a long string that starts with your email), and Outlook will display those events alongside your other calendars.

This method works on Windows, Mac, iPhone, and Android. The catch: your Google Calendar appears read-only in Outlook. You can see when you are busy, but you cannot create or edit events from the Outlook side — you have to go back to Google Calendar to make changes. If you only want to see your Google events without managing them in Outlook, this is the right choice.

Key Takeaways

  • The subscribe method lets you view your Google Calendar inside Outlook without editing, and works on all devices.
  • Full two-way sync requires you to add your Google account to Outlook's account settings, which lets you edit events in either app.
  • On Windows and Mac, you can also use the Outlook desktop app's calendar import feature to bring in a one-time snapshot of your Google events.
  • Phone apps (Outlook for iOS and Android) sync Google Calendar through your Microsoft account, not through a separate login.
  • If you use Outlook.com in a web browser, you cannot directly add Google Calendar — you must use the desktop or phone app.

Two-way sync: add your Google account to Outlook

If you want to create, edit, and delete events in either Google Calendar or Outlook and have them show up in both places, you need to add your Google account as a connected account in Outlook. On Windows, open Outlook and go to File > Account Settings > Account Settings again. Click New, choose Google, and sign in with your Google email and password. Outlook will ask for permission to access your calendar — click Allow.

On Mac, the process is similar: go to Outlook > Preferences > Accounts, click the plus sign, choose Google, and sign in. Once you add your Google account, your Google Calendar will appear in Outlook's calendar list, and any event you create or change in either app will sync to the other within a few minutes.

This two-way sync is the most seamless option if you use both Google Calendar and Outlook regularly. The trade-off is that you are giving Outlook permission to access your Google account, which means Outlook stores your Google login credentials. If you are uncomfortable with that, stick with the subscribe method instead.

On your phone: sync through your Microsoft account

Outlook for iPhone and Android syncs your Google Calendar through your Microsoft account, not through a separate Google login. Open the Outlook app, tap the menu icon (three horizontal lines), go to Settings, then Calendar, then Add calendar. Choose Google, sign in with your Google email, and allow Outlook to access your calendar. Your Google events will then appear in the Outlook app's calendar view.

On both iPhone and Android, this sync is two-way — you can create and edit events in the Outlook app and they will show up in Google Calendar, and vice versa. The Outlook app also lets you switch between your Google Calendar and any other calendars you have added, so you can view them all in one place or hide the ones you do not need to see right now.

One-time import: bring in past events without ongoing sync

If you only need to see your Google Calendar events once, or if you are switching from Google Calendar to Outlook permanently, you can import a snapshot of your Google Calendar instead of syncing it. On Windows or Mac, open Google Calendar in a web browser, click Settings (the gear icon), go to Import & Export, and click Export. Google will read a .zip file containing your calendar data in .ics format.

Then open Outlook, go to File > Open & Export > Import/Export, choose Import an iCalendar (.ics) or vCalendar file, and select the .ics file you just downloaded. Outlook will add all those events to your calendar. This import happens only once — future changes in Google Calendar will not appear in Outlook, and changes in Outlook will not go back to Google Calendar.

Why events might not show up

If you added your Google Calendar to Outlook but the events are not appearing, first check that your Google Calendar is not hidden. In Outlook, look at the calendar list on the left side of the screen. Your Google Calendar should have a checkmark next to it. If it does not, click the checkbox to show it.

If the calendar is checked but still empty, try signing out and signing back in. On Windows, go to File > Account Settings > Account Settings, right-click your Google account, and click Remove. Then add it again following the steps above. On Mac, go to Outlook > Preferences > Accounts, click your Google account, and click the minus sign to remove it, then add it again.

Another common issue: if you are using the subscribe method (read-only), make sure you pasted the correct calendar address. In Google Calendar, click Settings (the gear icon), go to Calendars, find your calendar, click the three dots next to it, and choose Settings. Scroll down to Integrate calendar and copy the full address next to Public address in iCal format. Paste that exact address into Outlook's subscribe field.

Outlook.com (web browser) does not support Google Calendar

If you use Outlook through a web browser at Outlook.com, you cannot add Google Calendar directly. The web version of Outlook does not have the same account-linking features as the desktop and phone apps. Your options are to use the Outlook desktop app for Windows or Mac, use the Outlook mobile app on your phone, or open Google Calendar in a separate browser tab and switch between them.

If you want a single calendar view in your web browser, consider using Google Calendar as your main calendar and opening Outlook.com only for email. Alternatively, you can use a third-party calendar tool like Calendly or Fantastical that can display both Google Calendar and Outlook calendars in one place, though these tools usually cost money and add another app to your workflow.

Frequently Asked Questions

Can I edit Google Calendar events from inside Outlook?

Only if you use the two-way sync method (adding your Google account to Outlook's account settings). With the subscribe method, your Google Calendar is read-only in Outlook, so you have to open Google Calendar to make changes. With two-way sync, you can create, edit, and delete events in either app and the changes will sync automatically.

Will my Google Calendar events show up in Outlook's meeting invitations?

Yes. Once you add your Google Calendar to Outlook, Outlook will check both your Outlook calendar and your Google Calendar when you are scheduling a meeting or checking your availability. This prevents you from accidentally double-booking yourself across the two calendars.

What happens if I delete an event from Outlook that came from Google Calendar?

With two-way sync, deleting an event in Outlook will also delete it from Google Calendar. With the subscribe method (read-only), you cannot delete events in Outlook at all — you have to delete them in Google Calendar. If you imported events as a one-time snapshot, deleting them in Outlook will not affect Google Calendar.

Can I sync multiple Google Calendars to Outlook?

Yes. If you have more than one Google Calendar (for example, one for work and one for personal), you can add your Google account once and Outlook will show all your Google Calendars. You can then hide or show each one individually in Outlook's calendar list.

Is it safe to give Outlook access to my Google account?

Google and Microsoft are both large companies with security practices, but you are giving Outlook permission to read and modify your calendar data. If you are uncomfortable with that, use the subscribe method instead, which only lets Outlook view your calendar without needing your Google password. You can also revoke Outlook's access at any time by going to your Google Account security settings and removing Outlook from your connected apps.
