It has been a tough week at Microsoft for sure. The company had to deal with a large Microsoft 365 services outage. Before that, the tech giant had to release a couple of hotpatch updates including KB5084897 that was issued to fix Bluetooth problems.
Speaking of which, Microsoft today has confirmed that the latest Patch Tuesday update for Windows 11 25H2 and 24H2 is causing connectivity problems related to the internet, and like the outage reported earlier, the bug does not allow signing in to use many of the free Microsoft apps which include Teams Free, OneDrive, Excel, Word, Edge, and Copilot.
We had already reported on several potential issues users had been having post this update which included reboot loops, system freezes, and more. However, this particular bug was not something we uncovered.
Microsoft has documented the issue in its newly opened issue where it says: "Following installation of Windows updates released March 10, 2026 (KB5079473) sign in with Microsoft accounts might fail for some Microsoft applications, including Microsoft Teams Free or OneDrive. As a result of this issue, sign in attempts will display an error message with text similar to "You'll need the Internet for this. It doesn't look like you're connected to the Internet". This appears even if the device is connected to the internet. ... Other applications affected include Microsoft Edge, Excel, Word, and Microsoft 365 Copilot. Whenever a feature in these applications requires Microsoft account sign in, the same message can be encountered."
Microsoft has issued a workaround for the problem which requires you to be connected to the internet when restarting the affected device, although it also adds that the problem may resolve itself. The company has explained: "This issue occurs when the device enters a specific network connectivity state, and may resolve on its own. If you encounter this issue, restart the device while keeping it connected to the internet. This should repair the device connectivity state and prevent the issue from occurring. However, please note that if the device is restarted without an active internet connection, it might return to a connectivity state where the issue can occur again."
