Outlook Web (Business account) not auto refreshing

It sounds like you've already tried a number of troubleshooting steps for your Outlook Web auto-refresh issue. Here are a few additional suggestions that might help:

1. Check Browser Extensions: Sometimes, browser extensions can interfere with web applications. Try disabling all extensions temporarily to see if that resolves the issue.
2. Browser Settings: Ensure that your browser settings allow for automatic updates and notifications from Outlook Web. Check if there are any settings related to background processes that might be affecting the refresh.
3. Network Settings: Since you've tried different networks, ensure that there are no firewall settings or security software on your local PC that might be blocking Outlook Web from functioning properly.
4. Clear Cookies: In addition to clearing the cache, clearing cookies may help resolve issues with web applications. Make sure to clear cookies for the specific sites you are having trouble with.
5. Test in Incognito/Private Mode: Open your browser in incognito or private mode to see if the issue persists. This can help determine if the problem is related to your browser's cache or settings.
6. Check for Windows Updates: Ensure that your Windows operating system is fully updated, as sometimes updates can resolve underlying issues affecting applications.
7. Try Different User Profile: If possible, create a new user profile on your Windows PC and see if Outlook Web behaves differently under that profile.

If none of these steps resolve the issue, you may want to consider reaching out to Microsoft support directly for more specialized assistance, especially since this problem seems unique to your setup.

Hi @Steven True,  

Welcome to the Microsoft Q&A forum.     

Thank you for contacting us regarding the issue where your Outlook inbox does not automatically refresh after returning from annual leave. I truly appreciate the detailed information you have provided and the troubleshooting steps you have already tried. 

Based on your description, the problem only occurs on your MSI Raider 66 laptop and not on other devices, which suggests that the issue is localized to your PC rather than your account or network. Outlook Web relies on real-time technologies such as WebSockets and service workers to update your inbox automatically. If these connections are blocked or interrupted on your machine, the inbox will not refresh until you manually reload the page. 

Given this situation, I would like to share a few additional methods you can try, which I hope will be helpful to you: 

1/ Check for security software interference 
If you have any third-party antivirus or web protection software installed, please temporarily uninstall it (not just disable) and restart your PC. These tools sometimes block real-time connections. 

2/ Reset network settings 

• Open Command Prompt as Administrator and run: 

netsh winsock reset 
netsh int ip reset 
ipconfig /flushdns 

• Then restart your PC. This will rebuild your network stack. 
• netsh winsock | Microsoft Learn 

3/ Clear SSL state and update DNS 

• Press Windows + R, type inetcpl.cpl, and press Enter. 
• In the Internet Properties window, go to the Content tab. 
• Click Clear SSL state. 
• 
• Restart your browser. 
• Change DNS to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) in your network adapter settings.

4/ Reset browser flags and policies 

• In Edge/Chrome, go to edge://flags or chrome://flags → click Reset all. 
• 
• Check edge://policy or chrome://policy to ensure no policy is blocking WebSockets or service workers. 
• 

5/ Test with a new Windows user account 
Create a new local user account on your PC, log in, and try accessing Outlook Web. This helps rule out profile-level issues. 

6/ Verify system time and proxy settings 

• Ensure your system clock is correct and synced. 
• Check Settings → Network & Internet → Proxy and confirm no proxy is enabled. 
• 
• Use a proxy server in Windows - Microsoft Support 

7/ Contact Microsoft Support   

If the issue persists even after these steps, it may stem from a deeper system-level cause. In this case, I recommend contacting your organization's IT administrator, who can submit a support request to Microsoft through the Microsoft 365 Admin Center. They’ll be able to access system-level information to investigate the issue thoroughly and provide assistance. At the very least, they can offer the most effective workaround to ensure your experience remains smooth and secure.
