New Teams not available in New Outlook

Dear @Jesse Pears,

To ensure I understand your request correctly and to support you as effectively as possible, I need more specific information from you:

• Are you using a personal or business/ school account?
• Is this issue happened recently?
• Could you share a screenshot of the issue?

When using New Outlook, using new Outlook, you should be able to go to Calendar > New event and turn on the Teams meeting toggle.

In the meantime, kindly try these steps:

1> Confirm the account type

Scheduling Teams meetings in Outlook is supported for Microsoft 365 Business Exchange work or school accounts. If you are using a personal Microsoft account, that can explain the issue by itself. Please check again the account you are using to sign in New Outlook and Teams. Schedule a Microsoft Teams meeting from Outlook - Microsoft Support [3cdc-baf1-613-883b]

If your Outlook is signed in ******@outlook.com / @hotmail.com / @msn.com or another non-work Exchange account, Outlook scheduling for Teams is not supported in the same way.

2> Make sure both apps use the same account

Teams meeting toggle in new Outlook appears only when you are signed in to both Outlook and Teams with the same work or school account. Teams Meeting add-in missing in new Outlook - Microsoft Support

3> Reinitiate the Outlook–Teams integration

Close Outlook.

Right-click the Teams icon and select Quit Teams.

Start Teams again and sign in.

Then start Outlook again.

I hope the information shared helps point you in the right direction. Please try the steps above and let me know if they work. If not, we can continue working together to narrow this down.

The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.

In new Outlook for Windows, there is no separate “New Teams add-in” to install. Teams integration is built in as a Teams meeting toggle in the event window.

Use these checks and fixes:

1. Confirm requirements for the Teams toggle
   In new Outlook, the Teams meeting capability only appears if:
   • Signed in to Outlook with a work or school account.
   • Signed in to new Teams client with the same work or school account.
2. Reinitiate Teams–Outlook integration
   If the requirements are met but the Teams meeting option is still missing:
   1. Close Outlook.
   2. In the Windows taskbar/notification area, right‑click the Teams icon and select Quit Teams.
   3. Start new Teams, sign in with the same work or school account used in Outlook.
   4. Start new Outlook again and check the calendar event window for the Teams meeting toggle.
3. Understand classic add‑in vs new Outlook
   • The Teams COM add‑in (classic “New Teams Meeting” button) is not supported in new Outlook. New Outlook uses the native Teams meeting toggle instead.
   • If using classic Outlook and the Teams Meeting add‑in is missing after moving to new Teams, follow the repair steps:
     1. Uninstall Teams Meeting Add-in from Settings > Apps > Installed apps.
     2. Close Outlook.
     3. Quit Teams from the system tray.
     4. Restart new Teams so it reinstalls the add‑in, then restart Outlook.
4. Account and mailbox configuration issues
   If the user has the correct license and is still missing the Teams meeting option even after reinstall and on multiple devices, the mailbox configuration may be corrupted. One known cause is an invalid DefaultOnlineMeetingProvider value. An Exchange Online admin can fix this with:

      Set-MailboxCalendarConfiguration -Identity <user@domain> -DefaultOnlineMeetingProvider TeamsForBusiness
   

   After this change, restart Teams and Outlook and recheck the calendar event window.
5. How to schedule once it works
   In new Outlook (desktop or web):
   1. Go to Calendar.
   2. Select New event.
   3. Turn on the Teams meeting toggle next to the Title.
   4. Choose the correct calendar/account, add details and attendees, then Send.

If, after these steps, the Teams meeting toggle is still missing in new Outlook while using a work/school account and new Teams, tenant‑level investigation by Microsoft 365 support is recommended.
