This post will walk through how to add your Office 365 calendar to your Google Calendar, something I recently had to do at work and found the online literature to be sorely lacking.
Prep Office 365 Calendar to be shared
Login to your Office 365 account and navigate to the Calendar page, click on the Gear in the top right:
Once selected, find the “Your app settings” on the bottom right-hand side of the page, click on “Calendar.”
Select “Publish Calendar” from the left-hand side menu. Then select the calendar you wish to share and set the permission level to the level you are comfortable with, anything but “Not Shared.”
Once the settings are correctly set, click ”Save”
Finally, copy the link to the right of ICS either by right-clicking on it and selecting “Copy Link Address” or highlighting it and hitting Ctrl+C. This is the link Google needs to access your calendar.
Enter Office 365 info into Google
Navigate to calendar.google.com, and again click the gear in the top right and select “Settings”
Once in the settings tab, switch to the “Calendars” tab at the top of the page.
Once on the Calendars tab, scroll down slightly to get to the “Other Calendars” section. On the right-hand side, you should see “Browse interesting calendars,” click on this
Once on the Interesting Calendars page, select the “Add by URL” link on the left-hand side.
Paste your copied Office 365 link into the dialog box and click “Add Calendar”
Google will process this for a moment, you can return to google.calendar.com
Your calendar should appear on the left-hand side of your calendar under the section “Other Calendars”
You can change the name of the calendar within Google Calendar by holding your mouse over the name and clicking on the delta that pops up, then selecting “Calendar Settings”
Simply type the name you would like in the box and click save
You can now see your Office 365 calendar on calendar.google.com and can turn it on within your Google Calendar app
