Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
I'm sorry you're having trouble accessing Microsoft Office. I understand that you want to pay for a yearly Microsoft 365 Personal subscription, but you're unable to sign in. I'll be happy to help you through this. First, could you please clarify a few things?
Are you trying to sign in to Microsoft Word or Excel on your computer, or through a website? When you enter your password, do you receive an error message, or does the sign-in window simply disappear? Have you previously paid for Microsoft 365 Personal, and are you trying to renew it, or would this be your first subscription?
Please check whether you can access your Microsoft account outside the Office applications.
Open Microsoft Edge.
Press Ctrl + Shift + N to open a private browsing window.
Select Sign in and try entering your email address and password.
Please let me know what happens.
