How to add Microsoft Teams add-in to Outlook?

Question

Microsoft Teams has disappeared from my outlook. When I schedule a meeting I'm not able to choose Teams virtual meeting.

Answer 1

Dear @Glen Witwer, 

Thank you very much for outlining the issue. I understand you no longer see the Microsoft Teams option when scheduling meetings in Outlook. 

Because the Outlook version you are using was not specified, I have outlined the solutions for both Classic Outlook and the New Outlook experience.  

Please ensure your operating system and Outlook application or browser are fully updated before trying any steps. 

Scenario 1: Classic Outlook  

• Step 1: Check whether the Teams button appears in the Calendar view 

To schedule a Teams meeting, please switch to the Calendar tab. 

Open Outlook > Go to the Calendar tab > Select New Meeting, New Appointment, or New Items > Appointment or Meeting. 

Note: Creating a meeting from the Email tab will not display the Teams meeting option. 

• Step 2: Verify the Microsoft Teams Meeting Add‑in 

Please open the Classic Outlook app > File > Options > Add‑ins. 

At the bottom, set Manage to: Disabled Items > Go. 

If Microsoft Teams appears in this list, select it and choose Enable. 

If it doesn't appear, continue with these steps: 

Return to File > Options > Add‑ins 

Set Manage to: COM Add‑ins and select Go. 

Ensure Microsoft Teams Meeting Add‑in for Microsoft Office is checked. 

Restart Outlook. 

• Step 3: Reinstall Office apps 

If the add‑in still does not load correctly, reinstalling Outlook can provide a fresh configuration. 

Uninstall Office apps, then reinstall them:    

Go to office.com> Apps > All apps > Install apps > Microsoft 365 apps > Apps & devices > Install Office.   

After installation, Outlook may open in the New Outlook interface. To return to Classic Outlook, please refer to this document link: Revert to classic Outlook - Microsoft Support 

Scenario 2: New Outlook 

• Step 1: Verify the Teams meeting option 

Please go to the Calendar tab > Select New event > Confirm the Teams meeting toggle appears. 

After saving the event, Outlook will automatically generate a Teams meeting link. 

• Step 2: Uninstall and reinstall Outlook app 

You can follow the same reinstallation steps listed in Scenario 1 if the Teams button remains missing. 

• Step 3: Try using Outlook on the web if you are using New Outlook for desktop app 

If the issue occurs in the New Outlook desktop version: 

Please try signing in using a private or incognito browser window, or clear your browser cache to ensure that outdated data does not create any conflicts.  

Sign in again at office.com using the work account.  

After signing in successfully, try opening an app such as Outlook from the Apps section. 

Try scheduling a meeting from the Calendar view.  

Note: The interface is similar to New Outlook on desktop, so the steps remain familiar. 

Scenario 3: If you are using a personal account 

Since your post is tagged as business-related, it would be helpful to confirm whether you are using a work or education account.  

Currently, scheduling Teams meetings from Outlook is supported only for Microsoft 365 business or education accounts.

Answer 2

Use the following steps depending on whether classic Outlook or new Outlook is in use.

1. Verify Teams/Outlook requirements

• Sign in to the Teams desktop app with a valid work or school (commercial) account.
• Make sure Outlook and Teams are both installed and up to date.
• Ensure Outlook is not running as Administrator while Teams is not; both apps must run in the same context.

2. If using new Outlook (with the “New Outlook” toggle) In new Outlook, there is no separate Teams add-in. Instead, a built-in Teams meeting toggle appears in the event window.

Requirements:

• Signed in to both Outlook and Teams with the same work or school account.
• Using the new Teams client.

If the Teams meeting toggle is missing even though these requirements are met, reinitiate the integration:

1. Close Outlook.
2. Right-click the Teams icon in the system tray/toolbar and select Quit Teams.
3. Start Teams and sign in.
4. Start Outlook and create a new event; the Teams meeting toggle should now appear.
5. If using classic Outlook (COM add-in model)

A. Check if the Teams Meeting Add-in is installed and enabled

1. In Outlook, go to File > Options > Add-ins.
2. At the bottom, next to Manage, select COM Add-ins and choose Go.
3. Look for Microsoft Teams Meeting Add-in for Microsoft Office.
   • If it appears and is unchecked, check it and select OK, then restart Outlook.

B. If the Teams Meeting Add-in is missing after updating to New Teams If the add-in does not appear in the COM Add-ins list at all after moving to New Teams, reinstall it via New Teams:

1. Open Settings > Apps > Installed apps in Windows.
2. Search for Teams Meeting Add-in.
3. Select the three dots (…) next to it and choose Uninstall.
4. Close Outlook.
5. Right-click the Teams icon in the system tray and select Quit to fully close Teams.
6. Start New Teams again. This forces New Teams to reinstall the Teams Meeting Add-in.
7. When Teams Meeting Add-in shows again under Installed apps, restart Outlook and confirm the Teams Meeting button is available when creating a meeting.

C. General troubleshooting if the add-in still does not appear

1. Confirm the Teams desktop app is installed and signed in with a commercial account.
2. Ensure Outlook and Teams are not running as Administrator (right-click each shortcut > Properties > Compatibility and make sure Run this program as an administrator is unchecked).
3. Fully quit both apps, then start Teams first, and then Outlook.
4. If needed, reinstall the Teams desktop client via Settings > Apps (uninstall Teams, then install the latest version and launch Teams before Outlook so the add-in can register).

If none of these steps restore the Teams option, contact the organization’s IT admin to check whether a tenant policy has disabled the Teams add-in or whether there are profile/registry issues that require admin-level repair.
