Breaking News:Windows 11 March Update Blocks Microsoft Account Sign-In in Office and Copilot Apps– What Just Happened

Microsoft’s Windows 11 March update has a confirmed issue affecting Windows 11 versions 25H2 and 24H2 with KB5079473. This issue causes sign-in failures in some Microsoft applications, including the free version of Microsoft Teams, OneDrive, Microsoft Edge, Excel, Word, and Microsoft 365 Copilot. After installing the Windows 11 March update, you might encounter a message saying, “You’ll need the Internet for this. It doesn’t look like you’re connected to the Internet,” even when your device is connected. This problem occurs when a device enters a specific network connectivity state that the Windows 11 March update does not handle well, causing some Microsoft applications to mistakenly identify the device as offline. It’s important to note that this issue only affects Microsoft accounts.

To resolve this issue, Microsoft recommends simply restarting your device. This should fix the connectivity state that causes the connection to Microsoft accounts to fail. However, there is a significant chance that the device might return to this specific networking state, resulting in repeated sign-in errors. Microsoft is working on a fix, which is expected to be released in the coming days. As the week ends, the release will likely be early next week. No server platforms are affected by this issue; it only impacts Windows 11 versions 24H2 and 25H2 with the March update KB5079473, OS Build 26100.8037.

This is yet another issue contributing to Windows 11’s reputation challenges. For instance, there have been several reports from the enthusiast community about problems with C: drive access on Samsung devices, where the “C:\ is not accessible – Access denied” issue has been acknowledged. Microsoft is working on a solution. The company reportedly claims that the Samsung Galaxy Connect application is responsible for the inaccessible C: drive, and the issue did not occur solely because of the Windows 11 March update but coincidentally happened alongside other accumulated issues.
