Microsoft acknowledged that the March update to Windows 11 disrupted access to Teams and OneDrive.

Problem Summary

After installing the cumulative update KB5079473 (Patch Tuesday) in Windows 11, some services stopped working correctly with Microsoft accounts. This affected Teams, OneDrive, Edge, Excel, Word, and Microsoft 365 Copilot: when attempting to sign in, a message appears stating “You’ll need an internet connection… It looks like you’re not connected to the Internet,” even though the network is actually available.

Who it Affects

The issue occurs only for users who use Microsoft accounts (e.g., the free version of Teams). Companies that use Entra ID (formerly Azure Active Directory) do not experience login problems.

How to Temporarily Resolve It

Restarting the computer usually fixes the error if the device remains connected to a network. If the device is powered off without an active connection, the problem can reappear because the system returns to an “offline” state.

Additional Updates from Microsoft

After releasing the main patch, the company issued two emergency fixes for Windows 11 Enterprise:

1) They address issues with Bluetooth device visibility.
2) They close several vulnerabilities in the Routing and Remote Access Service (RRAS).

Microsoft also published guidance on resolving a system‑disk access error on certain Samsung laptops caused by incorrect operation of the Samsung Galaxy Connect or Samsung Continuity Service applications.
