Using Classic Outlook on Windows for personal email, calendar, and contact management
Hello
I just found a solution .
Previously, we used a regedit file to modify CLSID KLClassRoot value on severals keys like C:\Users\xxxx\AppData\Local\Microsoft\TeamsMeetingAddin\1.0.22304.2\x64\Microsoft.Teams.AddinLoader.dll
But this folder doesn't exist anymore .
First of all, when you download the new Teams, it's only x86 version (32b) .
So in my case I have to uninstall all 32b Office Product, then re install in 64b .
I found a Teams 64b old version on Microsoft Official website, but doesn't work at all .
I have to go Teams Online, join a meeting, choose "download application" to get the good x64 version .
It worked for me
