Using Classic Outlook on Windows for personal email, calendar, and contact management
I have the same situation after starting with a fresh install of office on a new computer. In Outlook desktop app, the teams add in is not showing, so I can't schedule MS teams meetings directly from the desktop app. (have to go to MS teams and do it there).
If you open the add ins page from the desktop app, will bring to you the web-based client ad ins and, MS teams connector is not listed as an option to download.
Thank you for your help
