Google Calendar App Not Syncing? Here's How To Fix It Easily

Google Calendar is one of the Best Calendar apps and one of the reasons is that it offers quite some versatility regarding accessing calendar events from multiple platforms and devices.

You can view your work events on your phone and do the same on your laptop. Furthermore, you can sync your Outlook calendars with Google Calendar and access the Outlook events straight from Google Calendar.

Great accessibility aside, Google Calendar has some issues syncing the events, as sometimes events won’t sync across all your devices. You create an event on your laptop, which won’t appear on your phone.

Let’s go over the ways to fix the sync issues with Google Calendar, so your availability is streamlined across all your calendars.

How to fix Outlook Calendar not syncing with Google Calendar

If you’ve shared an Outlook Calendar with a Google Calendar, updates in Outlook take up to 24 hours to reflect to Google Calendar.

There are 2 ways to fix the Outlook Calendar not syncing with Google:

1. Use a Calendar Sync Tool

The easiest method to fix the Outlook Calendar not syncing with Google Calendar is by using a Calendar Sync Tool that syncs Outlook and Google Calendars in real-time, automatically.

This method is the easiest, as you won’t have to follow any manual steps each time you update the Outlook Calendar for the events to show up in Google Calendar. Tools like OneCal allow you to sync multiple Outlook and Google Calendars in real-time, without worrying that the availability is not streamlined across all your devices.

2. Manually sync Outlook and Google Calendar:

The second method of fixing Outlook not syncing with Google Calendar is by removing the Outlook Calendar from Google Calendar and connecting it again.

This method is manual, as you’ll have to manually sync Outlook and Google Calendar each time an update happens on Outlook. The reason is that it takes up to 24 hours for Outlook updates to be reflected in Google Calendar. By the time these updates are reflected, you might have run into scheduling conflicts or missed meetings because you weren’t aware of them.

To remove an Outlook Calendar from Google Calendar, follow these steps:

1. Open Google Calendar: You can open Google Calendar on the web by following this URL: https://calendar.google.com/
   
2. Find the "My Calendars" section: The My Calendars section is located on the left sidebar of the app
   
3. Find the Outlook Calendar you want to remove: All the calendars you’ve connected to Google Calendar are located below the My Calendars section in Step 2.
4. Hover over the Calendar and click the three dots.
   
5. Click "Settings".
   
6. Scroll until you reach the bottom of the page: After clicking Settings, please scroll until you reach the bottom of the page.
7. Click "Unsubscribe".
   
8. Click "Remove Calendar": After clicking Unsubscribe, Google Calendar shows a confirmation modal, asking if you’re sure to delete the calendar, Click Remove Calendar.
   

After removing the Outlook Calendar from Google Calendar, you should manually add the Outlook Calendar again. We wrote an article explaining in detail how to manually sync Outlook to Google Calendar, so please read that for the rest of the steps.
