Configuring preferences and options in Outlook.com
Wrong way of looking at things. MS is not providing this service for free, they're making money around it. Competitors are providing better services for free. MS by far is making more profits through their other products than most of competitors so squeezing people this way to push them towards paying for an email account is a cheap trick that will backfire on them. I personally seriously thinking about leaving my hotmail account that I held for over 20 years and go elsewhere.
In 2023, MS should increase their basic email storage to 50-100gb minimum; not reducing it and harassing people like that.
