This issue may be caused by a temporary problem with your network environment or device. If Outlook crashes or displays a loading icon when sending an email, try the following troubleshooting steps:

🛠 Step-by-Step Troubleshooting

1. Restart your device
   • A simple reboot can resolve temporary glitches.
2. Start Outlook in Safe Mode
   • Close Outlook completely.
   • Click the Windows icon and type: Outlook.exe /safe
   • Press Enter and confirm your profile name.
   • If Outlook works fine in Safe Mode, close it and try restarting normally.

If the issue persists after these steps, further investigation may be needed into your Outlook profile, add-ins, or network stability.
