    THERE IS ONE SIMPLE SOLUTION: I also have seen this issue among the users at my workplace. I’ve tried all the steps recommended with no success. There is one thing that all the solutions that I found didn’t suggest. RE-INSTALL OUTLOOK…! but there are a few things to check first. turn off Teams and Outlook 1) Ensure the user has the proper permissions to install software. 2) just incase make a back up of their contacts, & calendar items 3) uninstall OUTLOOK 4) reinstall Outlook 5) Turn On Teams 6) Open Outlook 7) open contacts and calendar and start sync of folders.

  2. you have to register the dll microsoft teams loader.dll

    just regsvr32 C:\Users\%username%\AppData\local\Microsoft\ersion number\x64(or x86)\Teamsmeetingaddin\microsoft…team…loader.dll

    after that just reboot the computer

    only if the above does not work

  3. This is the fix. Create this registry key:

    [HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins\TeamsAddin.Connect]
    “Description”=”Microsoft Teams Meeting Add-in for Microsoft Office”
    “FriendlyName”=”Microsoft Teams Meeting Add-in for Microsoft Office”
    “LoadBehavior”=dword:00000003

  4. Helⅼo thеre! I ccould һave sworn I’vе been tօ tһis blog beforе bᥙt after going throᥙgh many of tһe posts І realized
    іt’ѕ neew to me. Regardless, I’m defіnitely һappy І stumbled upon it and Ӏ’ll
    be book-marking it and checking Ьack often!

  5. None worked so far…

    Reinstalled teams – no success.

    Deleted teams files from C:\Users\%username%\AppData\Roaming\Microsoft\Teams – no success.

    Created key
    [HKEY_CURRENT_USER\Software\Microsoft\Office\Outlook\Addins\TeamsAddin.Connect]
    “Description”=”Microsoft Teams Meeting Add-in for Microsoft Office”
    “FriendlyName”=”Microsoft Teams Meeting Add-in for Microsoft Office”
    “LoadBehavior”=dword:00000003
    Still no luck…

    Tried registering DLL (either x64 ou x86) but it gives an error on both.

    Tried the MS tool, but it simply does nothing! xD

    I have .NET 4.8 framework installed…

    Im getting really frustrated here. Microsoft can be really emabarrasing sometimes… Teams should also be inside the office setup, just like Skype (even replacing it).

    Does anyone have any more tips?
    Thanks in advance

  6. What Office version are you using? The copy downloaded from Microsoft Store doesn’t support the add-in. You need to to install the “Click-to-Run” version to enable this add-in. I tried all workaround above and found no success. Then after I uninstall the Store version Office and installed the “Click-to-Run” version, the add-in is installed immediately.

  7. This worked for me:

    regsvr32 /n /i:user C:\Users\%username%\AppData\Local\Microsoft\TeamsMeetingAddin\1.0.20289.5\x64\Microsoft.Teams.AddinLoader.dll

  8. I tried all steps suggested here including reinstalling. Nothing works for me.
    In fact, the Teams addin does not even show in the list of existing addins. Anybody knows the name of the file/DLL that has the Teams addin ?

  10. deleting the contents of %appdata%\Microsoft\Teams worked for me – I had already tried reinstalling, reregistering, and other things but this was the one!

    Prem, can I suggest you change your instructions to use %appdata% and %localappdata% instead of saying “C:\Users\%username%\AppData\Roaming”? Then you don’t have to say “Replace the %username%”.
