Microsoft has identified an issue affecting signing in to apps using a Microsoft account. After installing the March 2026 Windows security update, some users might be unable to sign in to Microsoft apps and services. During sign‑in, users might see a "no internet" error even when the device has a working internet connection. This issue affects only Microsoft account sign‑in scenarios; organizations using Microsoft Entra ID for app authentication are not affected.
An out-of-band (OOB) update was released today, March 21, 2026, to address this issue. This cumulative update includes all protections and improvements from the March 2026 Windows security update released March 10, 2026.
This OOB update is available for Windows 11, versions 25H2 and 24H2 devices that receive standard Windows updates. It can be installed through Windows Update or the Microsoft Update Catalog. For more information, refer to the KB article KB5085516 (OS Builds 26200.8039 and 26100.8039) Out-of-band.
