This article will show you how to sync all of your Outlook calendars to your Microsoft Teams calendar. Although this article focuses on Outlook, the same technique works for syncing your Google calendar to your Teams calendar. You and your teammates can finally see your accurate availability without leaving Microsoft Teams.
The Microsoft Teams Calendar Does Not Show All Your Outlook Calendars
There are a lot of tweets and threads in the Microsoft support forum asking How to sync my Outlook Calendars and my Microsoft Teams calendar? Often, the underlying reason for the question is that the Microsoft Teams calendar only shows your default Outlook calendar (the calendar named “Calendar”). Events on on your non-default Outlook calendars (any calendars that you manually created, were shared with, you imported via URL, etc.) will not sync to your Microsoft Teams calendar.
Microsoft Teams Calendar does not show all your Outlook calendarsWorse, when your teammates view your availability using the Microsoft Teams Scheduling Assistant, they will see that you are free at when you are actually busy on one of your other calendars.

How to Sync your Google Calendar to Your Teams Calendar
If you are also wondering how you can sync your Google calendar to Microsoft Teams, the technique shown above works exactly the same for Google calendars. Just create a sync connection from your Google Calendar to your default Outlook calendar.
Once you’ve synced your other Outlook calendars and Google calendars to your default calendar, your Teams calendar and the Teams Scheduling Assistant will always be up-to-date with your true availability. No more jumping back and forth between Teams and Outlook or Google calendar. And no more getting double booked via the Teams Scheduling Assistant
Fixing a Team Calendar That’s Not Syncing with Outlook
If your Microsoft Teams calendar isn’t showing recent changes or events from Outlook, the issue is usually with how Outlook handles non-default calendars or cached data. Teams only displays events from your default Outlook calendar (the one named “Calendar”), so if your meetings or appointments are on another calendar, they won’t appear in Teams unless you synchronize your calendars.
First, confirm that the meetings exist in your default Outlook calendar. If they don’t, use CalendarBridge to sync your other Outlook or shared calendars into your default one. This ensures Teams can read all your events and display your correct availability.
If the events are on your default calendar but still aren’t appearing in Teams:
- Close and reopen the Teams app to force a refresh.
- Make sure your Teams and Outlook accounts are connected to the same Microsoft 365 tenant.
- Clear the Teams’ cache or sign out and back in.
- Check whether you have multiple Outlook profiles or accounts, as Teams will only sync from the account you’re currently signed into
Once everything is aligned, your Teams calendar should update automatically. If you want to keep every calendar in sync going forward, set up a real-time CalendarBridge sync so Teams, Outlook, and even Google Calendar all stay updated together.
How Calendar Sync Improves Collaboration in Microsoft Teams
When your calendar is truly synced across platforms, Microsoft Teams becomes more than a messaging and meeting tool, it becomes a real-time hub of team availability. Whether you’re managing internal meetings, external client appointments, or personal obligations, having a unified calendar inside Teams reduces friction, avoids double-booking, and enables faster scheduling decisions.
