How to Sync Outlook Calendar with Google Calendar

Typically, every day starts and ends with a look at your Google Calendar. However, it’s easy to get confused when using Google and Outlook calendars simultaneously.

The solution is simple—synchronize your Google and Outlook accounts. Keep reading if you want to discover how to sync both calendar apps. This article explains the Google/Outlook calendar sync process on various devices and tells you how to do it successfully.

Note: For a faster method that delivers quick results, skip the below process and check out the other listed options, including those for IOS/iPhone, Android, and Outlook.

Sync Outlook Calendar to Google Calendar using Google

Before you can sync Outlook to Google Calendar, you must acquire an ICS link using the Outlook website. Synchronizing the two calendars doesn’t require additional plug-ins or extensions, as both platforms utilize the open standard ICS format.

Once you have the correct Outlook ICS link URL, add it to Google Calendar.

Note: This method is impractical, especially since it takes 24-48 hours (or even longer) to update in Google. The only fix for this process is to remove the Outlook link in Google Calendar and add it again to update the synced Outlook Calendar.

If still interested in adding the Outlook ICS link to Google Calendar directly, do the following:

  1. Open your Office 365 account in a browser.

  2. Go to Outlook and click on Settings, then View All Outlook Settings.

  3. Click on Calendar, then Shared Calendars.

  4. In the Publish Calendar section, you can get the link you need.

  5. Select Calendar, then Can view all details, and then click Publish.

  6. Click on the ICS link (below the HTML link at the bottom) and choose “Copy” to use later in Google.

  7. Once you’ve acquired your Outlook calendar link, it’s time to finish the synchronization. Open Google Calendar.

  8. Tap on + next to “Other calendars” at the bottom of the page.

  9. Now, click on From URL.

  10. Paste the link saved and tap on Add calendar.

  11. In the Other calendars section in the bottom left area, you’ll see your Outlook calendar that you can select. The sync process is now complete.

New changes take 24 hours or longer to update in Google Calendar, but it does work. As previously noted, you can remove the ICS link and add it as a new calendar to get updated Outlook data if you don’t want to wait so long.

Of course, most people need new calendar changes as quickly as possible, and 24 or more hours doesn’t cut it. It takes so long because Google Stores it in the “Other calendars” category, which isn’t updated often enough. Google hasn’t implemented any changes to this particular setup and probably won’t. With that in mind, other alternatives deliver faster results that place calendars in the “My calendars” section versus “Other Calendar.”
