Classic Outlook on Windows 11 stopped updating inbox on startup

Question

I m running Outlook Classic on my new Windows 11 system on a new desktop, an older Surface Laptop running Windows 10, and have the Outlook app on my Android phone. Both the Surface and my desktop are included in my Windows 365 subscription.

A couple days ago Outlook Classic stopped updating the inbox on startup for my Windows 11 system. The Windows 10 system and the Android app have not been affected. No new apps, updates, or system/security settings have been changed by me. It can't be my internet provider as the other systems update immediately. How can I troubleshoot the cause of this issue?

Answer 1

Hi! Your app might be having a problem. Click on the Send/Receive tab > Send to all > A loading screen will appear in the bottom bar of Outlook; click on it > See if any synchronization errors appear.

You can try reconnecting your account.

ATTENTION: If your email account is POP, you must save the Outlook data file, usually in Documents > Outlook Files.

1. Press Windows + R > Type control > Click View By > Large Icons > Search for Mail (Microsoft Outlook). 
2. Click Email Accounts > New > Enter your credentials. 

• If you can't log in, select "Manual setup or additional server types" and follow the instructions. 

Answer 2

To troubleshoot the issue with Classic Outlook not updating the inbox on startup on your Windows 11 system, you can try the following steps:

1. Check Internet Connection: Ensure that your internet connection is stable and working properly on the Windows 11 system.
2. Update Outlook: Make sure that your Classic Outlook is up to date. Sometimes, updates can resolve bugs or issues.
3. Repair Outlook: You can try repairing your Outlook installation. Go to Control Panel > Programs > Programs and Features, select Microsoft Office, and then choose the Repair option.
4. Check Account Settings: Verify that your email account settings in Classic Outlook are correct. Sometimes, incorrect settings can prevent the inbox from updating.
5. Disable Add-ins: Some add-ins can interfere with Outlook's functionality. Start Outlook in safe mode (hold down the Ctrl key while starting Outlook) to see if the issue persists. If it works in safe mode, consider disabling add-ins one by one to identify the culprit.
6. Check for Conflicting Software: Ensure that there are no other applications or security software that might be conflicting with Outlook.
7. Recreate Outlook Profile: If the problem continues, consider creating a new Outlook profile. This can resolve issues related to corrupted profiles.

If none of these steps resolve the issue, you may want to consult Microsoft Support for further assistance.
