Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Welcome Mike Harriman,
Thank you for posting on Microsoft Q&A, and for explaining the background so clearly. I understand how frustrating it is to sign in successfully and still be blocked from managing your account and subscription. I'd like to help you sort this out.
To narrow it down, could you tell me:
- Which task fails? For example, managing your Microsoft 365 Family subscription or sharing, changing email addresses, security settings, or billing.
- What exactly happens? Is there an error message or code, a blank page, or are you sent back to the sign-in page? A screenshot with personal details hidden would help.
- Which email address do you sign in with, the new Outlook.com address or the custom-domain address?
- Does it happen in every browser and on every device you've tried, including your phone?
Looking forward to your update.
