Disable Add Personal account option
As an organisation we would like to disable the option for users being able to sign into additional Teams accounts.
This is a terrible idea. I own my own laptop, which I bought with my own money. Yet my organization has enabled this option which stops me from using Teams with a personal account on my laptop, and there's no way for me to undo that. Please don't make this even more restrictive. On the contrary, give me the ability to unlink Teams from my org (and no, logging out doesn't do that).

Please stop adding features that create more issues, especially when there is no option for the admin to control it.
