If you are having issues with Microsoft Teams Meeting Addin missing in Outlook, here are a few tips:
- Make sure Microsoft Teams Meeting Addin is installed and present in the Control Panel
- Navigate as admin to C:\Program Files\WindowsApps\MSTeams_23320.3021.2567.4799_x64__8wekyb3d8bbwe (Version number might have changed)
- Copy MicrosoftTeamsMeetingAddinInstaller.msi
- Run the following command:
- msiexec.exe /i “MicrosoftTeamsMeetingAddinInstaller.msi” ALLUSERS=1 /qn /norestart TARGETDIR=”C:\Program Files (x86)\Microsoft\TeamsMeetingAddin\1.23.33413\” (Version number might have changed)
- Also, make sure this key is set on the user side. You could make a GPO or Intune script for that
- HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins\TeamsAddin.FastConnect
- “Description”=”Microsoft Teams Meeting Add-in for Microsoft Office”
- “FriendlyName”=”Microsoft Teams Meeting Add-in for Microsoft Office”
- “LoadBehavior”=dword:00000003
Thank you so very much!
Found the MicrosoftTeamsMeetingAddinInstaller version number with “Orca” in the table “Upgrade”.
That worked perfect, the Addin returned to Outlook.
