Hi, westsidetkd.
It sounds like you were seeing a connection error for your iCloud email on your PC. If you’re still experiencing this, we’d like to see how we can help.
You’re absolutely correct in that your iCloud email settings are automatically configured with on your PC when you use iCloud for Windows. You won’t be able to alter the settings, but sometimes if you deselect Mail in iCloud for Windows to temporarily disable your account. Wait a few minutes and enable it again. iCloud for Windows should automatically reconfigure the server settings.Â
It sounds like you may not be using your iCloud email account. If you have no plans to access it, you may want to leave it deselected.Â
If you’re using it with Outlook on your computer, this article may also help:
