Microsoft Teams Meeting Add-in for Microsoft Office not Installing

Hello, I'm having an issue with a laptop where it has the latest version of Microsoft 365 Office running with the latest version of Teams installed but the "Microsoft Teams Meeting Add-in for Microsoft Office" application is not installed. This application installing when Teams installs is important as it allows for the integration of teams into Outlook with features such as creating Teams Meetings from Outlook. On my desktop when I uninstall both "Microsoft Teams" and the "Microsoft Teams Meeting Add-in for Microsoft Office" applications, reinstalling Teams brings both applications back. However, on my Laptop I have tried to uninstall and reinstall both Microsoft 365 Office as well as Teams at the same time as well as separately and I cannot get the Add-in application to install with it, thus when I go to outlook on the laptop it lacks the functionality between the Teams and Outlook. I have tried to look at get Add-ins on outlook for a Teams Add-in but it does not exist, the "Microsoft Teams Meeting Add-in for Microsoft Office" application also shows up on the Installed Apps list for the computer, so I don't believe it functions the same as an Outlook Add-In. I tried to submit pictures to this post showing the Installed Apps on both devices, but I received an error when I tried. If anyone know of a way to get the Microsoft Teams Meeting Add-in for Microsoft Office" application independent on installing Teams that would be awesome, or if there are any other fixes to the issue. Thank you so much.

Dear Jerry_672,

You're very welcome! I'm glad I could offer some suggestions.

Regarding step 5, manually installing the add-in – I apologize for the confusion. Unfortunately, there's no separate, publicly available installer specifically for the "Microsoft Teams Meeting Add-in for Microsoft Office." It's supposed to be bundled and installed automatically with the Teams desktop application. So, there's no separate download link for it. The fact that it's not installing even after reinstalling Teams is the core of the problem.

Since you've already diligently tried all the standard troubleshooting steps (reinstalling Teams and Office, checking add-ins, etc.), and given that there's no separate add-in installer, it strongly indicates that something more complex is happening, possibly on the server backend or with your specific configuration.

Based on information from articles like this one: Teams meeting add-in missing from Outlook and new Teams - Microsoft Teams | Microsoft Learn], and considering the steps you've already taken, it's likely that this issue requires deeper investigation than we can provide on this forum. As this forum has limited access to those server-side configurations, and given that the add-in isn't available separately, the most effective way to resolve this would be to open a support ticket with Microsoft directly through the Microsoft 365 admin center. They have the tools and expertise to look at your specific setup and diagnose the underlying cause.

Here's how you can create a service ticket:

  1. Go to the Microsoft 365 admin center: [Get support - Microsoft 365 admin | Microsoft Learn]
  2. Navigate to Support > Service requests.
  3. Create a new service request, detailing the issue you're experiencing with the missing Teams Meeting Add-in. Be sure to mention all the troubleshooting steps you've already taken.

If you don't have admin access to your Microsoft 365 account, please reach out to your organization's IT administrator and ask them to open the support ticket on your behalf. I know it's an extra step, but this will give you the best chance of getting this resolved quickly and efficiently. Microsoft's support engineers will be able to delve into the issue much more deeply. Thank you for your patience and understanding!

Thank you for your understanding and patience. I really hope they can get this resolved for you quickly!

    Jerry,

          I face a similar problem.  But per your original post.  "If anyone know of a way to get the Microsoft Teams Meeting Add-in for Microsoft Office" application independent on installing Teams that would be awesome, or if there are any other fixes to the issue. "

    There is such an installer. named: MicrosoftTeamsMeetingAddinInstaller.msi

    When you install the Teams app, it is placed in this general location:

    C:\Program Files\WindowsApps\MSTeams_25031.805.3440.5290_x64__8wekyb3d8bbwe

    Of course that MSTeams directory is specific to the installed version of teams.

    You can attempt to run that installer manually on your computer, and it does work sometimes. I tried it on my computer, and it worked as expected.

    I have another computer, same problem as yours. The Outlook Add On for Teams is missing. I ran the above installer, and it failed. I then noted in the Application logs that Microsoft was trying to run the above application (to install the AddIn) whenever Outlook was launched. However it was failing to install, and generation and Event 11001 error message.

    Still looking into the reason why the AddIn will not install.

    Dear Jerry_672,

    Many thanks for your reply!

    I understand that you are still experiencing this issue with the Microsoft Teams Meeting Add-in not appearing in Outlook despite multiple attempts to reinstall both Teams and Office.

    Here are a few additional steps that might help resolve this issue:

    1. Sometimes, add-ins can be disabled by Outlook. Go to File > Options > Add-ins, then at the bottom of the window, select Disabled Items from the Manage dropdown and click Go. If the Teams Meeting Add-in is listed there, enable it.
    2. Ensure that the registry keys for the Teams Meeting Add-in are correctly set. You can check the following registry paths:
      • HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins\TeamsAddin.FastConnect
      • HKEY_LOCAL_MACHINE\Software\Microsoft\Office\Outlook\Addins\TeamsAddin.FastConnect
      Make sure the LoadBehavior value is set to 3.
    3. Sometimes, repairing the Office installation can resolve issues with add-ins. Go to Control Panel > Programs > Programs and Features, select Microsoft Office, and choose Change. Then select Quick Repair or Online Repair.
    4. Performing a clean boot can help identify if other applications or services are conflicting with the Teams Add-in. Instructions for performing a clean boot can be found here.
    5. If the add-in is not appearing, you can try to manually add it. Download the Teams Meeting Add-in from the Microsoft website and install it manually.
    6. If this is a work or school account, ensure that there are no group policies in place that might be preventing the add-in from being installed or loaded.

    If these steps don't resolve the issue, it might be helpful to escalate the case to Microsoft Support for further assistance. Let me know if you need any more detailed instructions on any of these steps!

    Good morning, I appreciate your response! I saw the fix for uninstalling the "Microsoft Teams Meeting Add-in for Microsoft Office" as mentioned in the first link provided, the issue is that the application is never installed in the first place when Teams is installed so I can't uninstall it to fix this. In this state I have tried multiple uninstalls and reinstalls of Teams and the Add-in never pops up, as well as uninstalling and reinstalling Office at the same time as reinstalling Teams and the add-in never pops up.

    It now allows me to send screenshots, so I attached the picture that the Add-in is not present. I will look into the classic teams fix however this laptop is about two months old so I don't think it would have ever had the classic version of teams installed.

    1. What operating system are you running (e.g., Windows 10, Windows 11)? Both devices are running Windows 11
    2. How was Microsoft 365 installed? Was it a full installation or a click-to-run installation? Is Microsoft 365 a personal subscription or is it part of a work/school account? Microsoft 365 was installed using the full installation, it is part of a work/school account.
    3. Did you install Teams from the Microsoft Store or download it directly from the Teams website? Have you tried running Teams as administrator to check if it works? I have tried downloading Teams from both the Microsoft store as well as through the Teams website, as well as running Teams as an administrator.
    4. Have you checked for and installed any pending updates for Microsoft 365 Office applications? There are no pending updates for office.
    5. Are you logged into the same account on both your laptop and desktop? Do you have the necessary administrative privileges on your laptop? I am logged into the same account on both the laptop and desktop, on both devices the user account are members of the Administrator group
    6. Have you tried to manage Office Add-ins within Outlook itself? (Go to File > Options > Add-ins > Manage: COM Add-ins > Go... and see if the Teams Meeting Add-in is listed there.)" The Teams Meeting Add-in is not listed in the Outlook Add-ins
    7. Have you tried performing a clean boot to rule out any conflicts with other applications or services? I have not tried a clean boot but would performing one have the Add-in show up? Or would I then need to reinstall and uninstall Teams to see if it worked?

    Again, I appreciate your response, let me know if there is any other information that could help resolve this issue, thank you!

    Dear Jerry_672,

    Good day! Thank you for posting to Microsoft Community. We are happy to help you.

    I am sorry to hear you are experiencing this issue. It's really inconvenient when software integrations don't work as expected, especially when you rely on features like scheduling Teams meetings directly from Outlook. I can imagine how this missing functionality is impacting your productivity.

    Have you tried uninstalling the Teams Meeting Add-in by right clicking the Windows Start button and select Settings> Apps> Installed Apps, then search for the Teams Meeting Add-in > Click the three dots and select Uninstall? Please refer to Teams Meeting add-in is missing in Outlook Desktop after updating to New Teams - Microsoft Support.

    Alternatively, based on this article, Teams meeting add-in missing from Outlook and new Teams - Microsoft Teams | Microsoft Learn; When a version of classic Teams is uninstalled, the Teams meeting add-in is also uninstalled. The uninstallation process removes the registry keys that are shared across all versions of the Teams meeting add-in. Therefore, when new Teams and Outlook start, the computer doesn't find the installed add-in to load. Please check this resolution****as shared in the above article and let me know and provide the answers to the following for further investigation:

    1. What operating system are you running (e.g., Windows 10, Windows 11)?
    2. How was Microsoft 365 installed? Was it a full installation or a click-to-run installation? Is Microsoft 365 a personal subscription or is it part of a work/school account?
    3. Did you install Teams from the Microsoft Store or download it directly from the Teams website? Have you tried running Teams as administrator to check if it works?
    4. Have you checked for and installed any pending updates for Microsoft 365 Office applications?
    5. Are you logged into the same account on both your laptop and desktop? Do you have the necessary administrative privileges on your laptop?
    6. Have you tried to manage Office Add-ins within Outlook itself? (Go to File > Options > Add-ins > Manage: COM Add-ins > Go... and see if the Teams Meeting Add-in is listed there.)"
    7. Have you tried performing a clean boot to rule out any conflicts with other applications or services?

    We look forward to hearing from you. Let me know if you have any other questions. Please understand that our initial response may not always immediately resolve the issue. However, with your help and more detailed information, we can work together to find a solution. Thank you for your cooperation.
