Let me assist you on your concern regarding the error in page message that appears on the left side corner of your Outlook.com interface. One of the possible reasons on why this error message appears is that there's an issue with your browser.
To make sure that your browser settings doesn't contribute to this issue, we suggest that you optimize your browser. To optimize your browser, please refer to this
