Please add feature to pin the UI fonts to a minimum size.
UI 9pt font for Ribbon menu (Activity, Chat, Teams, Meetings, Calls, Files, etc.)
Ctrl + will increase font size while Ctrl - decreases font size. This change affects the entire UI, not just the message text.
In other apps such as MS Word, increasing/decreasing zoom for document text does not affect all ribbon bars and menu items, yet in Teams, this is exactly what happens. Only app ever to have noticed this behavior where zooming text affects UI menu and ribbon bar fonts.
