How to add a Microsoft 365 Outlook Calendar in Google Calendar

Managing separate calendars can lead to scheduling mishaps and potential conflicts. Simplify your life by integrating your Microsoft Teams meetings from your Outlook Calendar into your Google Calendar.

You'll need access to both your Outlook and Google Calendar accounts for this. Remarkably, no additional software, plugins, or third-party tools are required.

Both Microsoft and Google calendars support the iCal format, a universal standard for exchanging calendar information. You can easily sync your Outlook Calendar to Google Calendar using an iCal subscription link.

Share an Outlook Calendar

To begin, you'll need to secure the iCal link from your Outlook Calendar. Although older versions of Outlook permitted direct calendar sharing from the desktop application, this functionality is now exclusive to the Outlook web app for sharing outside your organization.

Login to your Office 365 account and navigate to Outlook. Click on the app launcher, symbolized by nine dots in the top-left corner, and then select the Outlook icon.

Click on Settings > View all Outlook settings.

Open Calendar > Shared Calendars.

In the "Publish a calendar" section, choose the calendar you want to share (if you've only got one Calendar set up it will just be called "Calendar"), select "Can view all details" in the second dropdown, and click "Publish."

This will create two links: an HTML link and an ICS link. The HTML link allows people to view your calendar in a browser and the ICS link will enable people to import your calendar into their calendar program.

Click the ICS link, and a menu will appear. Select the "Copy link" option to copy the link to your clipboard.

Add Outlook Calendar to Google Calendar

Open up Google Calendar and click on the "+" sign next to "Other calendars."

In the menu that appears, click "From URL."

Paste the ICS link you copied from Outlook and click "Add calendar."

Exit out of Settings and check that the calendar has been added.

Your Outlook calendar will remain in sync with your Google Calendar as long as the subscription is active. While the update speed can vary, any changes made in your Outlook calendar should generally be visible in Google Calendar within a short time frame, depending on Google's update frequency.

Customizing the Calendar's Look and Feel

Your calendar is now successfully linked, but you might want to update its display name for easier identification. To do this, hover over the calendar, click the three dots that appear adjacent to it, and then select "Settings."

In the "Name" text box at the top of the page, change the name of the calendar to something more meaningful. Then click the back arrow in the top left to exit the Settings.

The calendar now displays your new name.

Remove an Outlook Calendar from Google

Hovering your cursor over the calendar will make an "X" icon appear. Clicking on this icon will unsubscribe you from the calendar. To resubscribe, you'll need to go through the setup process again and input the ICS URL.
