I am not sure what I did, but the Teams add-in is no longer visible nor available to be added in Microsoft Outlook. How do I add it back in? Or can I?

    Hi @Bob Heizman ,

    Welcome to the Microsoft Q&A forum.

    Based on your description, the Teams Meeting Add-in is missing in Outlook.

    Please follow the steps below to resolve the issue:

    1. Make sure you are signed in with the correct account.
    2. Try signing out and then signing back into both Outlook and Teams at the same time.
    3. Clear the Outlook cache . You can refer to the following documentation to clear the Outlook cache: Clear the Office cache - Office Add-ins | Microsoft Learn
    4. Uninstall the Teams Meeting Add-in from Windows
      • Step 1: Press Windows + I
      • Step 2: Go to Apps > Installed apps, then search for Meeting Add-in
      • Step 3: Click the … icon > select Uninstall User's image

    Restart New Teams. This will force New Teams to reinstall the Teams Meeting Add-in which should fix the issue. When you see Teams Meeting Add-in in the list of installed apps again, restart Outlook and it should be working again.

    I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this.   

    Thank you for your patience and your understanding. If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.

    I look forward to continuing the conversation.

    Use the following steps depending on which Outlook experience is in use.

    1. Verify whether new Outlook is being used
    • In new Outlook, the Teams integration is built in as a Teams meeting toggle in the event window; there is no separate add-in to install.
    • Requirements for the toggle to appear:
      • Signed in to Outlook and Teams with the same work or school account.
      • Using the new Teams client.
    • To reinitiate integration if the toggle is missing:
      1. Close Outlook.
      2. Right-click the Teams icon in the toolbar and select Quit Teams.
      3. Start Teams and sign in.
      4. Start Outlook.
    1. If using classic Outlook for Windows (separate add-in)
    • Confirm the Teams Meeting add-in is installed and enabled:
      1. In Outlook, select File > Options.
      2. Select Add-ins.
      3. Under Manage, choose COM Add-ins and select Go.
      4. Locate Microsoft Teams Meeting Add-in for Microsoft Office.
      5. If it is unchecked, check it and select OK, then restart Outlook.
    1. If the add-in is missing from the COM Add-ins list
    • Ensure the Teams Meeting Add-in is installed at the OS level:
      • Open Settings > Apps > Installed apps and look for Microsoft Teams Meeting Add-in for Microsoft Office.
    • If it is missing or not working after updating to new Teams:
      1. Right-click Start > Settings > Apps > Installed apps.
      2. Search for Teams Meeting Add-in.
      3. If present, select the three dots and choose Uninstall.
      4. Close Outlook.
      5. Quit Teams from the system tray.
      6. Restart new Teams; this forces new Teams to reinstall the Teams Meeting Add-in.
      7. When Microsoft Teams Meeting Add-in for Microsoft Office appears again in Installed apps, restart Outlook and confirm the add-in is available.
    1. If the add-in still does not appear
    • Make sure Outlook and Teams are not running as administrator and that Teams is the desktop client (not only the web client).
    • If issues persist after these steps, follow the troubleshooting guidance in the referenced articles or contact IT/admin support to check for policy or configuration issues.
