I don't even know man. I used to click a teams link and teams would pop up. Now a splash screen for "new" teams comes up and none of my programmable mouse shortcuts work and it seems like sometimes it launches through a browser, other times it doesn't. I have personal and two work accounts which makes things complex too.
Edit; oh, and if I click on teams icon it says do you want to use "new teams" or "classic teams"? If I click on classic a brief screen pops up and in small print it says classic teams died in March of 2023 - Rip. Then the whole app just shuts down. It feels very amateur.
The "new" version isn't even a native app... It's just the web version. It's missing a whole heap of features from regular Outlook, like support for native add-ins. It doesn't feel like a native app; the UI doesn't follow the design standards of any desktop OS.
Apparently the prompt for asking is triggered because the "new" version is a different executable than the shortcut you're using is pointing to. So you could fix that by creating a new shortcut.
Another fix would be to get rid of Teams, but when you're on a corporate license there's not much we can do about that
god you'd think these fly by night open source hippies would commit to their ideals a little more, you know? the only real option is paid software maintained by full time employees who get fucking paychecks. nothing else is ever gonna work outside of your weird Foss imagination land. 'Microsoft' was a cute dream, but it just isnt sustainable.
