Microsoft: Problems with Authenticator for Microsoft 365 services

Microsoft admits to problems with authentication using Authenticator in certain web browsers for Microsoft 365 services. Instead of accessing the desired service, those affected receive an error message.

On the status page for Microsoft services, the company states, “We're having issues, but we're working on it”. This means that the end customer version of Microsoft 365 is affected.

Microsoft 365: login disrupted

Microsoft describes the problem as follows: “Users are unable to authenticate with the Authenticator app when signing in to Microsoft 365 services in some browsers.” More specifically, the Redmond-based company explains that those affected receive an error message when signing in with Google's Chrome or Microsoft's Edge. It reads: “We have sent a sign-in request to a Microsoft app that you use to approve sign-in requests, but we have not received your approval.”

To sign in any way, Microsoft suggests signing in with a web browser besides Chrome or Edge. You can also choose to authenticate using other methods, such as a password, one-time code or passkey.

According to the latest incident report, the issue began on Monday last week. Microsoft's developers are currently testing a bug fix “to resolve the impact and expect the deployment to be completed by our next update.” That would be today, Thursday, at around 21:30 Central European Winter Time.

At the end of last November, there were already disruptions to Microsoft 365 services. Outlook and Teams in particular were affected, but Exchange Online was also affected. At the end of July 2024, Microsoft cloud services were also disrupted worldwide.
