Outlook has been hanging since start of this week on emails. Performed restarts and I see no error msgs. Tried restarting Windows 11 (25H2, 26200.7623, Windows Feature Experience Pack 1000.26100.275.0) and thought problem resolved. Now Outlook hangs at loading profile. What can I do?

Hi,

Many users have reported the same issue where Classic Outlook POP account profiles hang or freeze after installing the Windows 11 update KB5074109.

Microsoft has already released a fix for this issue. Please check if you have the KB5078127 out-of-band update installed by going to Settings > Windows Update > Update history. Installing this update should resolve the problem.

If you do not have this update yet, you can download and install it from the Microsoft Update Catalog: https://www.catalog.update.microsoft.com/Search.aspx?q=KB5078127

    If Outlook is hanging at the loading profile stage, you can try the following troubleshooting steps:

    1. Create a New Outlook Profile: Sometimes, the existing profile may be corrupted. You can create a new profile by following these steps:
      • Open Control Panel and click on Mail.
      • Click on Show Profiles.
      • Select the profile you want to remove and click Remove (be cautious as this will remove associated data files).
      • Click Add to create a new profile, enter a name, and follow the prompts to set it up.
    2. Run the Classic Outlook Advanced Diagnostics Troubleshooter: This tool can help identify issues with your Outlook configuration. Make sure you are using the same Windows device where classic Outlook is installed. Follow the instructions in the Get Help app to run the troubleshooter.
    3. Check for Updates: Ensure that your Windows and Outlook are updated to the latest versions. Sometimes, updates can resolve known issues.
    4. Repair Outlook: You can also try repairing Outlook through the Control Panel. Go to Programs and Features, find Microsoft Office, and select the option to repair.
    5. Disable Add-ins: Start Outlook in safe mode (hold down the Ctrl key while starting Outlook) to see if an add-in is causing the issue. If Outlook works fine in safe mode, disable all add-ins and enable them one by one to identify the culprit.

    If these steps do not resolve the issue, you may need to consider reinstalling Outlook or seeking further assistance from Microsoft Support.
