Teams Standalone Outlook Addin

manchesterBazza  + all

I know it's an old post but seeing no solution posted yet. Here's how I implemented this for an environment (x64) where Teams was not showing up on Outlook 2019.

Download the New Teams x64 client via https://learn.microsoft.com/en-us/microsoftteams/new-teams-bulk-install-client

Extract just the MicrosoftTeamsMeetingAddinInstaller.msi file from the downloaded MSIX file - I used 7-Zip to do so. Right click the MSIX > 7 zip > Open > Extract required file. 

Note : [https://learn.microsoft.com/en-us/officeupdates/teams-app-versioning#windows-version-history] - As of 20 July 2024 - currently the latest version of Teams is 24165.1414.2987.41 and the MicrosoftTeamsMeetingAddinInstaller.msi version is 1.24.14501

To install Teams Meeting Addin from command-line, you will first need the version number to install to the correct folder - its not easily visible in the file properties of the MSI. So, I opened the MSI in Notepad2 (editor of choice can be used) - and searched for ProductVersionMicrosoftManufacturer, as shown below - The version of the MSI is right alongside (it eventually shows up the version number in Add/Remove programs, so you could deploy it, figure out the version from there, uninstall, and then put it in the right location below using the script shown)

Then from an elevated command prompt to install system-wide for all users run the following command after adjusting for your environment  - 

MSIEXEC /I "<path>\MicrosoftTeamsMeetingAddinInstaller.msi" /passive /norestart TARGETDIR="C:\Program Files (x86)\Microsoft\TeamsMeetingAddin\<versionnumber>\"

Once that's done, you should be good to go with the "standalone" Teams Meeting Addin deployed. 

Worked well for me. YMMV.
