Office365 multi-factor authentication outage

Microsoft's Office365 login service has been down all day. (UK)

If you've been to work today and you use Outlook, OneDrive and other Office365 services from Microsoft, you'll know that it has been down for most of the day, in the UK. it's a global issue, too. (check your timezone)

As of now, 6pm (UK, time), the service is down.

It's fine if you log into your Microsoft Office365 without multi-factor authentication (MFA), however if multi-factor authentication is enabled on your account, the chances are, you haven't been able to log in today to access your Outlook emails or OneDrive, as well as other related services.

This is because, when MFA is setup, it requires you to, do one of a few options

- answer a phone call to prove its said user accessing the account

- type in a code from a text message

- type in a code from the Microsoft authentication app

- approve or deny your sign-in request using the Microsoft authentication app

If non of the above has been completed, you won't be signed into your account until one of the above have been actioned.

Your Office365 administrators will have access to the Microsoft Office365 Admin Centre. This is the place where it all happens. It warns admins of problems, planed works and service outages within the Office365 system. And for those whom have access, this worldwide issue, was, and still is, certainly on there!

For those who don't have access, you can visit where Microsoft provide updates every hour, regarding outstanding issues, such as this one.
