• Using Office 365 and can’t log on? (Again?) Looks like multi-factor authentication is down again

    For the second time in as many weeks, I’m seeing widespread reports that folks can’t log on to Office.

    Mary Jo Foley reports on ZDNet:

    Starting around 9:15 a.m. ET, a number of Office 365 customers began reporting on Twitter that they were unable to sign into that service because of an MFA issue. Office 365 is one of a number of Microsoft services that uses Azure Active Directory MFA to authenticate.

    You can see the current status report here. At the moment we’re treated to this delightful ditty:

    Starting at 14:25 UTC on 27 Nov 2018 a subset of customers using Multi-Factor Authentication may experience intermittent issues signing into Azure resources, such as Azure Active Directory, when Multi-Factor Authentication is required by policy. Impacted customers may encounter timeout errors. Engineers are aware of this issue and are actively investigating mitigation options. The next update will be provided in 60 minutes, or as events warrant.

    Here we go again.
