Who This Affects and What It Fixes
This guide is for small-business employees who open their Outlook calendar and find the Microsoft Teams meeting button is missing. Following the steps below will enable or repair the Teams Meeting Add-in for Outlook so you can schedule Teams meetings directly from your calendar.
How the Add-in Works
The Microsoft Teams Meeting Add-in for Outlook is automatically installed when you install the Microsoft Teams desktop application—no separate download is required. For it to appear correctly, Teams must be installed while you are signed in with the same email address you use for Outlook.
How to Enable or Install the Add-in
If the Teams button does not appear in your Outlook calendar, follow these steps:
- Sign out and restart both apps. Sign out of Microsoft Teams and Outlook, then sign back in to both. Close and reopen each application fully.
- Open Outlook Add-ins settings. In Outlook, go to File > Options > Add-ins.
- Check your COM Add-ins. At the bottom of the Add-ins page, find the Manage dropdown, select COM Add-ins, and click Go.
- Enable the Teams add-in. In the COM Add-ins list, check the box next to Microsoft Teams Meeting Add-in for Microsoft Office, then click OK.
- Install Teams if it is not listed. If the add-in does not appear at all, download and install the Microsoft Teams desktop application, then repeat the steps above.
Troubleshooting If the Button Still Does Not Appear
- Check Disabled Items. In Outlook, go to File > Options > Add-ins. Change the Manage dropdown to Disabled Items and click Go. If the Teams Meeting Add-in appears there, select it and click Enable.
- Run Teams as an administrator. Close Outlook completely. Right-click the Microsoft Teams application and select Run as administrator. After Teams loads, reopen Outlook and check for the button.
- Verify the add-in installation path. The Teams Meeting Add-in should be pointing to its correct location on your computer:
C:\Users\Username\AppData\Local\Microsoft\TeamsMeetingAdd-in. If the path shown in your COM Add-ins list differs from this, the installation may be corrupted and Teams should be reinstalled.

Common questions
Do I need to download the Teams Meeting Add-in for Outlook separately?
No. The Microsoft Teams Meeting Add-in for Outlook is installed automatically when you install the Microsoft Teams desktop application. If it is missing, it may be disabled rather than absent—check your COM Add-ins and Disabled Items lists in Outlook before reinstalling.
Why does the Teams add-in keep getting disabled in Outlook?
Outlook can automatically disable add-ins that cause it to start slowly or crash. Check File > Options > Add-ins > Manage: Disabled Items to see if the Teams Meeting Add-in has been turned off, then re-enable it. Running Teams as an administrator before opening Outlook can also prevent it from being disabled again.
What should I do if the Teams Meeting Add-in does not appear in the COM Add-ins list at all?
If the add-in is not listed under COM Add-ins, download and install the Microsoft Teams desktop application. Make sure you are signed in to Windows with the same email address you use for Outlook during the installation, then restart both Teams and Outlook.
