What likely happened is one of these two cases:
- The MSN commenting/profile state was restricted or removed on the MSN side.
- MSN article comments and account restrictions are handled by MSN’s own moderation systems.
- When comments stop working, profiles appear missing, or the site starts prompting to create an account again, Microsoft Q&A and Windows settings cannot show the reason or reverse it.
- The accepted guidance for MSN comment/profile issues is to use the Feedback option on an MSN page so the MSN team can investigate.
- The underlying Microsoft account sign-in state changed.
- If MSN cannot recognize the signed-in account, it can behave as if no profile exists.
- If the username is not recognized or the account appears missing, use the Sign-in Helper tool.
- If the Microsoft account has not been signed in to for more than two years, it may have been deleted and can no longer be reopened.
- A closed Microsoft account can only be reopened during its 30-day or 60-day grace period.
Since cache/history clearing was already tried, the supported next path is:
- Open an MSN page with comments.
- Use the Feedback option at the bottom right.
- Report that:
- the MSN Community Profile now prompts to create an account,
- previous comments/interactions are gone,
- no restriction notice was received,
- the issue has lasted more than a month.
- If the Microsoft account itself is not being recognized, use the Sign-in Helper tool from the Microsoft account sign-in support page.
If the Microsoft account was closed or deleted due to inactivity, the old profile/comments would not be recoverable through browser troubleshooting.
