my outlook keeps dropping internet access and requires me to restart in order to reconnect

Question

My Outlook app keeps disconnecting from my internet server and requires a restart to reconnect.

Outlook also shows multiple Outlook apps open at one time when I go to Task Master.

This just started after the latest update that was pushed.

Outlook also seems to not sync with my email provider very often and often requires me to close the app and then reopen it just to recieve emails.

Dear Anthony Miller,

Thank you for posting to the Microsoft Q&A.

I understand how disruptive it is when Outlook consistently drops its connection and requires a full restart just to sync your emails. The behavior you described—where multiple Outlook processes appear in Task Manager—is a clear sign that the application is hanging in the background and failing to close properly.

To provide the most accurate solution, could you please confirm which version of Windows you are currently using? If you are on Windows 11 and recently installed the KB5074109 update, you are likely experiencing a known issue that causes Outlook to freeze, lose internet connectivity, and fail to sync with POP/IMAP providers.

The good news is that the engineering team has released a permanent fix for this behavior. If your system is currently stuck on the problematic build, please follow these steps to install the KB5078127 patch released on January 24, 2026:

• Open Windows Settings.
• Go to Windows Update.
• Click Check for updates.
• Look for and install Security Update KB5078127.
• Restart your computer once the installation is complete.

Updating to this latest version should resolve the sync issues and prevent the "ghost" Outlook processes from staying open in your Task Manager.

If you have already updated and the issue persists, we need to clear those "multiple apps" manually to refresh the connection:

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Go to the Details tab.
3. Find every instance of Outlook.exe, right-click them, and select End Task.
4. Once the list is clear, restart Outlook.

Tip: If you find that Outlook still struggles to sync after the update, go to File > Account Settings > Account Settings. Select your email and click Repair. This will force Outlook to re-handshake with your email provider's server.

I hope updating to the KB5078127 restores your connectivity and stops the application from hanging. If you continue to see prompts after checking these settings, please do not hesitate to let me know

It sounds like you're experiencing connectivity issues with your Outlook application, which may be related to the recent update you mentioned. Here are some steps you can take to troubleshoot the problem:

1. Run Windows Update: Ensure that your Outlook client software and Windows operating system are up to date. An outdated version can cause connectivity issues.
2. Check for Service Issues: If multiple users in your organization are experiencing similar problems, it might be due to a service issue with Microsoft 365. You can check the Microsoft 365 Service health status for any ongoing issues.
3. Run Microsoft 365 Diagnostics: Use the Microsoft 365 diagnostics tool to perform automated checks that can help identify and resolve connectivity issues.
4. Repair Outlook Profile: If your Outlook profile is corrupted, it might cause disconnection issues. Consider creating a new Outlook profile to see if that resolves the problem.
5. Check Task Manager: If you notice multiple instances of Outlook running in Task Manager, it could indicate that the application is not closing properly. Make sure to end any unnecessary processes before reopening Outlook.
6. Update Office Installation: Ensure your Office installation is updated to at least version 2008 (Build 13127.20508) or later, as older versions may have unresolved issues.

If these steps do not resolve the issue, you may want to consider reaching out to Microsoft support for further assistance.
