Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
FYI, no need to upgrade to remove adverts if you use Chrome; I use an extension called 'Webmail Ad Blocker' which, as the author describes, "Block ads on the right hand side of the screen when using Yahoo Mail, Hotmail, Outlook.com and Gmail thereby expanding your message space." The author has several extensions I've also been using for years. They're so good I send in an annual donation in appreciation of his great work. (I believe there are similar extensions for Firefox as well, but I stopped using FF long ago so don't hold me to it). Hope that helps!
