Dear @Anonymous
Thank you so much for contacting Microsoft Q&A Forum.
Please understand that our forum is a public platform, and we will modify your question to cover your email address in the description. Please notice to hide these personal or organization information next time you post error or some information to protect personal data.
Based on your description, it appears that your email address is associated with a business account rather than a personal one. Additionally, I conducted a test and found that when using a Microsoft business account, access to the personal portal page at login.live.com is restricted. This behavior aligns with the image you provided.
Here is my result:
Therefore, I suggest that you should check that your email address can access to the portal for business account (also known as work or school account) via: portal.office.com
If it redirects to a university login page or asks for organization credentials, it’s a business account
I hope this information can help you.
Wish you a pleasant day!
