How to Add Office 365 Calendar to Google Calendar – Easy Sync

When users want to move away from Microsoft one of the prominent questions is how to add Office 365 calendar to Google calendar. Especially if their organization plans to migrate Office 365 to G Suite any time soon. 

However, neither Microsoft nor Google allows direct inter-app subscriptions. So the shift of calendar app data becomes more difficult. There are still a few means to sync the calendars with each other we will cover both individual mergers. And the one that organizations require for bulk transfer.   

Prerequisites to Sync Calendars with Each Other

You need to have access to the following if you are about to perform this task.

First, ensure that the Outlook account is accessible along with the calendar(s). Next up repeat the same for Google account and calendar app.

To locate the Calendar app in Office 365 you first have to sign in to your Outlook account and use the dashboard to get to the Calendar area.

On the other hand, for Google, the process is relatively simpler, you can directly log in to the calendar app as it exists as an independent entity. 

How to Add Office 365 Calendar to Google Calendar Step-by-Step

The entire process is divided into two parts. Follow the instructions below to quickly sync the Outlook 365 calendar with Google.

Part 1 Outlook (Office 365) Calendar 

• Step 1. Log in to your Microsoft 365 Outlook account.
• Step 2. From the left-most pane select Calendar.
• Step 3. Click on the Cog icon at the top right corner.
  
• Step 4. In the settings pane switch to Shared calendars tab.
• Step 5. Then in the Publish a calendar section select the Calendar and Permissions.
• Step 6. Click Publish.
  
• Step 7. Click on the ICS link and copy it.
• Step 8. A popup appears verifying a successful copy operation.
  

The rest of the steps are to be done on Google Calendar so switch to it.

Part 2 Google Calendar

• Step 1. Log in to the Google Calendar web app.
• Step 2. Click on the cog icon at the top right corner.
• Step 3. Choose settings from the drop-down.
  
• Step 4. From the left pane expand the Add calendar option.
• Step 5. Select “From URL”.
• Step 6. Paste the link you got from Microsoft Calendar in place of “URL of calendar”.
• Step 7. Press the Add calendar button.
  
• Step 8. Use the Go Back arrow at the top left corner and return to the main Calendar screen.
• Step 9. In the Main menu area expand the Other calendars section.
• Step 10. There you can find the now synced Outlook 365 calendar.

Sometimes the newly added events may take time to appear. So, take your cursor on top of the newly added calendar and click on the 3 vertical dots that appear on the right side.

Choose “Display this only” from the popup and hide other calendar events. Then scan through the filtered calendar to check for all events belonging to the newly added one.

Alternative Way to Sync Outlook 365 Calendar with Google Account

Although the Internet Calendar Subscription service generates a separate calendar in the Google account. As the recipient is not an Outlook.com user, the sync may take more than three hours to complete. So here we give you some steps that sync the events almost instantaneously. 

The approach we use will make the Gmail address a part of all Outlook events. This will send an invite for every Outlook calendar event you wish to see in the Google account. The process is given below.

• Step 1. Login to Outlook
• Step 2. Open the Calendar by clicking on the icon at the left pane.
• Step 3. Click on any Existing event
   
• Step 4. Tap the Edit button (the one with the pencil icon)
• Step 5. Click on More options.
  
• Step 6. In the Invite Attendees area, add the Gmail address and press Send. 
• Step 7. The event will pop up inside the calendar app of the target Gmail account.

Note once a shared event is created like the one we make here it is no longer possible to delete the event directly. Instead, you get the option to cancel where you have to send a message to all invitees i.e. the Gmail address.

However, the two major limitations that users need to watch out for are:

• Entirely manual users have to repeat the steps for each event individually.
• This method populates the Gmail account with multiple email invite requests.
