The "Teams (new)" is absurd. Have we not learned not to name things this way by now? I say this as someone as guilty as anyone of having created an iterative series of files with "Final_1.txt", "Final_2.txt", "Final_1-new.txt" suffixes in times of mental sketch-padding. I would never release a product into the wild with any of those in the title, though.

The same goes for other office products too. For example, there is a business version of Outlook and a personal (?) version of it. They have the same name, the interface is similar enough to not be sure what you have, and the only reliable way to know is to check where you downloaded the installer from. Some business accounts apparently do not work with the personal version. Colleagues were just standing clueless as to why their company office accounts could not sync when they had to reinstall stuff on a computer.

I don't understand why they keep doing this. I guess because the names are recognisable enough that they want them advertised as such for both use-cases, but it is confusing.

It's as if they saw how badly they messed up the Lync -> "Skype for business" transition and thought, "Yeah let's try that again".

This trend in MS software is utterly embarrassing. Every time I see these icons I cannot believe someone approved this approach.
