Q: Cannot access Apple email in iCloud

Hello wgoulart,

Thank you for using Apple Support Communities!

It sounds like messages are not loading for you at www.icloud.com.

I found this article while researching what could be causing this issue:

iCloud: Troubleshooting iCloud Mail

Cannot access iCloud Mail at iCloud.com

Make sure there are not any current issues listed for iCloud Mail in the System Status at the iCloud support site. 

If you can't access Mail via iCloud.com

1. Make sure you are accessing iCloud.com with a supported browser.
2. To make sure that Safari is up to date, choose Software Update from the Apple () menu and install all available Safari, security, and OS X updates. Instructions for updating other browsers should be available from the built-in or online help for those browsers.
3. If your iCloud Mail issue occurs only when using a particular browser, try clearing that browser's cache. For Safari 6 or later, choose Reset Safari from the Safari menu. Enable the option "Remove all website data", then click Reset. For Safari 5 and earlier versions, choose Empty Cache from the Safari menu. Instructions for other browsers should be available from the built-in or online help for those browsers.
4. Some Internet configurations can (inadvertently or purposely) prevent access to certain websites or services, such as iCloud Mail. If you're having issues accessing your iCloud Mail from one location or Internet connection but not others, contact your Internet Service Provider or network administrator for assistance.

Take care,

Sterling
