Users of Microsoft Office 365 and Microsoft 365 in Europe have been unable to access their mailboxes for more than a day, with a borked domain controller apparently the reason.

Surprisingly, the Microsoft Office 365 status website said there were no known issues.

But the Twitter account for Microsoft 365 said it had been determined that a subset of the domain controller infrastructure had become unresponsive, with the result that user connections were timing out.

In November last year, Microsoft had issues with the Office 365 service, with customers complaining they were unable to sign in to their accounts.

A number of cloud services offered by the Redmond software giant use the MFA offered by Azure Active Directory to authenticate by default.

Two days before that, users of the company's Exchange Online service were unable to access their email for more than 12 hours.

And a week prior, Microsoft cloud customers using multi-factor authentication found themselves locked out of their accounts.

Additionally, a lightning strike near one of Microsoft's South Central US data centres in September led to a massive outage in regions around the globe.

The Azure service was hit by a fire suppression incident in 2017. It also suffered prolonged downtime in 2013.
