Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
I suggest that nobody should reply to this thread because I see no evidence that anyone from Microsoft or its affiliates is monitoring it. Many of the posts here are not relevant to the original question. To answer that, I found that the following works (which differs a little from my post on page 5):
Click on https://support.microsoft.com/contactus Sign in to your account (if you don't have a paid account you will probably not be helped)
Choose "Get Home Support"
Type in a short version of your problem
Click on "Get Help"
Scroll down to "Sign in to Contact Support"
Choose a product
Under Category, choose "Manage Profile Info". Otherwise, you will probably get an AI that doesn't fit your question.
Click "Confirm" then "Chat with an agent"
I know this seems unduly complicated and redundant, which is probably intentional, but it is what it is.
I deleted my BitLocker keys from my Microsoft account, what can I do now? Please help me.
