The Outlook integration you need is usually called the Microsoft Teams Meeting add-in. It adds a New Teams Meeting button to Outlook so you can create a Teams meeting without switching to the Teams app.

On Windows, the add-in is installed with the Teams desktop client. On Outlook on the web, new Outlook, and Outlook for Mac, the Teams meeting option is normally built into the calendar experience rather than installed as a traditional COM add-in.

Before you start

Check these points before troubleshooting the add-in:

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  • Install and sign in to the Microsoft Teams desktop app if you use classic Outlook for Windows.
  • Sign in to Outlook with the same work or school Microsoft 365 account used in Teams.
  • Use a Microsoft 365 account and plan that includes Teams meeting functionality.
  • Close and reopen both Teams and Outlook after installing or updating either application.

Personal Microsoft accounts, organizational restrictions, expired licenses, and disabled add-ins can all prevent the Teams button from appearing.

Logitech Zone Wireless Certified Microsoft Teams Bluetooth Headset
  • SUPPORT WORK FROM ANYWHERE WITH SYNC: Whether employees are in the office, at home, or somewhere else, Sync device management software helps everyone stay connected by letting you ensure their Logitech video collaboration personal devices are being used and up to date.
  • Open workspaces are great for collaboration, but not so great when the noise around you makes it hard to concentrate. Active noise cancellation substantially reduces unwanted ambient sound, so you can get focused and stay focused.
  • Great for Music and Talking with immersive sound for listening to music and a noise-canceling mic that ensures that your voice is heard on the other end of a call—not the noise around you.
  • On ear controls to adjust volume, start/end calls, and invoke Teams. Plus button controls for power, active noise cancellation (ANC), wireless Bluetooth pairing, and mute on/off or use the flip-to-mute mic feature.
  • Certified for Microsoft Teams ensures it’s easy to pick-up or answer Teams meetings, calls, messages, and notifications with a single press to the Teams button. Or apply a longer touch to invoke Cortana voice skills.

Add the Teams meeting option to classic Outlook for Windows

  1. Download and install the Microsoft Teams desktop app for Windows.
  2. Start Teams and sign in with your work or school account.
  3. Quit Outlook completely. If it remains open in the notification area, right-click the Outlook icon and choose Close window or exit it from the taskbar.
  4. Quit Teams as well, then start Teams again. This allows the Teams meeting integration to register with Office.
  5. Open Outlook.
  6. Select Calendar.
  7. Select New Teams Meeting on the Outlook ribbon. In some Outlook layouts, the command appears under New Items > Teams Meeting.

Outlook should open a meeting invitation containing a Teams meeting link. Add attendees, a subject, and a time, then select Send.

If the button is not on the ribbon

  1. In Outlook, select File > Options.
  2. Select Add-ins.
  3. At the bottom of the window, set Manage to COM Add-ins.
  4. Select Go.
  5. Look for Microsoft Teams Meeting Add-in for Microsoft Office.
  6. Tick its checkbox and select OK.
  7. Restart Outlook.

If the add-in appears under Disabled Items, return to File > Options > Add-ins, set Manage to Disabled Items, select Go, choose the Teams add-in, and select Enable. Then check the COM Add-ins list again.

Use Teams meetings in new Outlook

New Outlook for Windows does not use the same COM add-in controls as classic Outlook. To schedule a meeting:

7. Check organizational policy

If the button is missing for multiple users, an administrator may have disabled Teams integration, restricted Teams meeting creation, or assigned a license without the required service. Ask the Microsoft 365 administrator to check the user’s Teams and Exchange Online licensing, Teams meeting policy, and Outlook add-in deployment.

Common situations that look like an add-in problem

Symptom Likely cause What to do
The Teams button appears in Teams but not Outlook Outlook’s COM add-in is disabled or not registered Check File > Options > Add-ins, restart, and repair Office if necessary.
The button is available but meetings have no usable link Account, licensing, or service problem Verify that Teams and Outlook use the same work account and contact the administrator if the issue persists.
Only one user is affected Local installation, disabled add-in, or cached account issue Restart, update, enable the add-in, and reinstall Teams if required.
Everyone is affected Tenant policy, licensing, or Microsoft 365 service issue Have an administrator review Teams policies, licenses, and service health.
The Teams option is missing in new Outlook but classic Outlook works Different integration model or an Outlook rollout issue Update new Outlook, verify the account, and use Outlook on the web as a temporary workaround.

Remove the Teams meeting option from Outlook

In classic Outlook, go to File > Options > Add-ins, select COM Add-ins in the Manage box, select Go, clear Microsoft Teams Meeting Add-in for Microsoft Office, and select OK. This removes the Outlook command but does not uninstall Teams.

In new Outlook or Outlook on the web, simply turn off the Teams meeting option when creating an event. Existing Teams meetings retain their meeting details unless you remove them from the event.

FAQ

Why is the Teams add-in not showing in Outlook?

The most common causes are that Teams is not installed or signed in, Outlook disabled the COM add-in, the two apps use different accounts, or an administrator has restricted the integration. In classic Outlook, check File > Options > Add-ins and review both Disabled Items and COM Add-ins.

Do I need to download the Teams Outlook add-in separately?

Usually no. The Teams Meeting add-in is installed or registered with the Teams desktop client on Windows. New Outlook, Outlook on the web, and Outlook for Mac generally expose Teams meeting creation through the calendar interface instead of requiring a separate Windows COM add-in download.

Can I add a Teams meeting to an existing Outlook meeting?

Open the meeting in Outlook, select the Teams meeting command or switch, and save or send the update. If the command is unavailable, create the meeting in Teams and copy its joining link into the Outlook invitation as a workaround.

Why can I create Teams meetings in Outlook on the web but not classic Outlook?

The web version does not depend on the same local COM add-in. Classic Outlook may have a disabled, missing, or damaged Teams Meeting Add-in for Microsoft Office. Enable it under File > Options > Add-ins, then restart Outlook.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Can an administrator deploy the Teams add-in for everyone?

Yes. Microsoft 365 administrators can control Teams availability, meeting policies, licensing, and Office add-in deployment. If the option is missing across an organization, the administrator should review those settings rather than reinstalling Teams on every computer.

The Bottom Line

For classic Outlook on Windows, install and sign in to the Teams desktop app, restart Teams before Outlook, then enable Microsoft Teams Meeting Add-in for Microsoft Office under File > Options > Add-ins if necessary. In new Outlook, Outlook on the web, and Outlook for Mac, create an event and turn on the Teams meeting option. If the command remains unavailable, check the account and license, repair Office, and ask the Microsoft 365 administrator to review organizational policies.
