Sync Teams calendar with Mac OS calendar - Still an issue and not working

It seems that you are experiencing issues with syncing the Teams calendar with the macOS native Calendar app. While the integration of Teams calendar appointments with the iOS Calendar app works smoothly, the same may not be true for macOS. Currently, Teams is designed to integrate primarily with Exchange for calendaring, and the syncing process can sometimes be problematic depending on the settings and configurations of your Microsoft 365 account.

Here are a few troubleshooting steps you might consider:

1. Verify Account Setup: Ensure that your Microsoft Exchange or Microsoft 365 account is set up correctly on your Mac. You can try removing and re-adding the account again to see if that resolves the issue.
2. Check Calendar Permissions: Make sure that the necessary permissions are granted for the Teams app to access your calendar.
3. Use Microsoft Remote Connectivity Analyzer: You can run a connectivity test using the Microsoft Remote Connectivity Analyzer tool to check if there are any issues with the connection between Teams and your Exchange mailbox.
4. Update Software: Ensure that both Microsoft Teams and your macOS are updated to the latest versions, as updates can sometimes resolve integration issues.
5. Contact Support: If the problem persists, consider reaching out to Microsoft Support for further assistance.

While this may not be a direct solution to the integration issue, these steps can help identify and potentially resolve the syncing problems you are experiencing.

Hi @Andy McFarlane,  

Welcome to the Microsoft Q&A forum.

Thank you very much for sharing your experience with us. I truly appreciate your feedback and understand how frustrating it can be when Teams calendar appointments don’t integrate properly with the macOS Calendar app, especially since it works seamlessly on iOS and other services. 

To clarify, the Teams calendar is powered by your Exchange Online (Outlook) mailbox. While iOS Calendar handles Exchange integration more smoothly, the macOS Calendar app currently has limitations and known sync issues with Exchange accounts. These issues are primarily related to Apple’s Calendar app on macOS, not Microsoft services, which is why Outlook for Mac and the Teams app remain the most reliable options for scheduling and joining meetings. 

Given this situation, here are my recommendations, which I hope will be helpful to you: 

1/ Outlook for Mac or Teams app option 

When you schedule meetings in these apps: 

• Teams meeting links are automatically generated and added to your event details. 
• Real-time sync with your Microsoft 365 account ensures updates appear instantly across all devices. 
• You can manage invites, join meetings with one click, and access advanced features like meeting options and chat all within the same ecosystem. 

In contrast, the macOS Calendar app only reads basic event data from Exchange and does not have a built-in Teams add-in, which means it cannot create or fully integrate Teams meeting links. 

You can refer to this Microsoft's article: How Exchange and Microsoft Teams interact - Microsoft Teams | Microsoft Learn 

2/ Use Power Automate (Advanced workaround) 

If you prefer using Apple Calendar, you can try an advanced workaround that some organizations use Power Automate to insert Teams links into Apple Calendar events, although this is not a built-in feature. 

In case you require more in-depth guidance or support for these steps, I’d recommend posting your query in the Microsoft Power Automate Community. This is a dedicated channel for Power Automate discussions. The reason I suggest posting a new topic there is that in the general Q&A Forum, resources and expertise on Power Automate are limited. In the Microsoft Power Platform Community Forum, you’ll find the most qualified group of respondents, and other partners who regularly read the forums can share their knowledge or learn from your interaction. 

I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, feel free to share them in the comments on this post so I can continue to assist you.   

Thank you again for your time and for raising this important usability concern.
