Why am I getting notifications saying 'I'm offline' when I'm not?

Question

My OneDrive has stopped syncing- when I click into OneDrive to fix the error, I get a message saying that I am not online, however I am online, and have other online applications working just fine.

Answer 1

Can you go check your Windows Settings > Windows update, and see if you might have  KB5085516 available to install?

KB5085516 was released on March 21st to address Microsoft account sign in issue among some apps caused by KB5079473 https://support.microsoft.com/topic/march-21-2026-kb5085516-os-builds-26200-8039-and-26100-8039-out-of-band-09e85404-1cb6-4ed4-9ca5-3e40d74307b9

Answer 2

The “I’m offline” or “not connected to the Internet” message appears when OneDrive or Office apps cannot reach Microsoft’s online services, even if the general Internet connection is working. This usually means either:

1. The app itself is failing to sign in or reach its service endpoint.
2. There is a temporary issue with Microsoft’s services or with the specific account sign-in component.

From the provided context, there are two especially relevant patterns and fixes:

1. Known sign‑in issue fixed by a Windows update
   A recent Microsoft Q&A thread describes OneDrive and other Microsoft apps incorrectly reporting “not connected to the Internet” while the device is online and the user can sign in via a browser. The moderator notes this was caused by a specific Windows update and fixed by installing an out‑of‑band update:
   • Check Settings → Windows Update and see if update KB5085516 is available.
   • If it is listed, install it and restart the PC. This update was released specifically to fix Microsoft account sign‑in issues in some apps that were introduced by update KB5079473.
2. OneDrive not running or stuck / sync component issue
   Even when the network is fine, OneDrive may not be running correctly or its sync engine may be stuck:
   • Confirm that OneDrive is actually running:
     • On Windows, look for the white or blue OneDrive cloud icon in the notification area at the far right of the taskbar.
     • If it is not visible, click the Show hidden icons arrow.
     • If the icon still does not appear, start it manually: select Start, type OneDrive, and select OneDrive from the results.
   • If OneDrive is running but sync is stuck or failing, standard remediation is:
     • Make sure the latest OneDrive app is installed.
     • If sync remains broken, unlink and re‑link OneDrive to refresh the connection and credentials.
     • If a particular file or folder is blocking sync, temporarily move it out of the OneDrive sync folder, let sync complete, then move it back.
3. Service‑side or location‑specific connectivity issues
   For OneNote and similar apps, an error like 0xE4010641 (Network Disconnected) appears when the app cannot reach OneDrive, SharePoint, or the network location where data is stored, even if the rest of the Internet works. In such cases:
   • Wait a few minutes and try a manual sync again.
   • If the data is on SharePoint or a network share, verify that the server is online and reachable.
4. General Office “offline” messages
   Office apps show “troubleshoot your Internet connection” when they cannot reach Office.com/Office Online services. This can happen if:
   • The device is offline or behind a network configuration that blocks Microsoft services.
   • The specific Office online category or template being requested is no longer available.
     Even then, locally installed content and templates remain available.

In summary, for OneDrive showing “I’m offline” while the PC is online:

1. Install Windows update KB5085516 if it is offered in Windows Update, then restart.
2. Verify that OneDrive is running and updated to the latest version.
3. If needed, unlink and re‑link OneDrive to refresh the account connection.
4. If the problem persists, check whether this is limited to Microsoft apps (OneDrive, Outlook, OneNote) while browsers work, which strongly suggests a sign‑in component issue resolved by the above update.
