The Microsoft Exchange admin portal is currently inaccessible from some browsers after Microsoft forgot to renew the SSL certificate for the website.

Starting at 8 AM EST today, Microsoft Exchange admins who attempted to access the admin portal at admin.exchange.microsoft.com suddenly found that their browsers were issuing warnings that the connection was not private due to an expired SSL certificate.


Depending on the browser, users are blocked from accessing the site as a security precaution or shown an alert that the data may not be secure. For example, Google Chrome will stop you from accessing the site altogether, while Firefox will warn you about the insecure connection.
Microsoft states that they are aware of the issue and are working on a fix.
As a temporary workaround, Microsoft states you can access the admin portal from the Sign in to Outlook URL as well.
