iCloud mail not working on iOS "Cannot Get Mail"

Nope. Did that. Not a fix.

After I reset my password on http://iforgot.apple.com all my apps like Calender, Contacts and Find my iDevices worked and synced fine...Mail however would tell me my password is incorrect and if I tried to launch mail from icloud.com it would throw that "cannot load mail" message

OK just got off the phone with Apple about the issue and their solution was simple and worked. It seems even though all THEIR messages tell you to go to iforgot.apple.com to reset your AppleID that site does not work for people who converted their MobileMe accounts over to iCloud. (Site seem to work perfect for new iCloud users though). For anyone who needs to reset their icloud password the right way will have to use appleid.apple.com to do so. Once I re-reset my account on appleid.apple.com (at the request of the apple rep on the phone who called me back on a sunday even though my computer was out of warranty - Love Apple) I was able to get back into mail on all my iDevices and iCloud. I hope this helps everyone who've been having issues.

Thanks, but... I already changed my password TWICE on appleid.apple.com. No luck. Still no mail. Getting a bit frustrated. I don't really need that email address, but nevertheless this really undermines my confidence in Apple.

YES! This worked great. I have been chating with Apple support and pulling my haid out due to the e mail not working. All of my family members are also having the problem so I am off to fix it for them to! Thanks for your help apple communite! You are all amazing.

Quick question to clarify: should @Mac addresses continue working as they always have? Or is converting to an @me access required? I just couldn't imagine that Apple would expect everyone to go through the address change process when it could easily be avoided. Hadn't yet been able to find a definite answer. Thanks!

worked perfectly jeremy158 - thanks buddy. Silly Apple

I've just begun to experience this same error this morning (both while trying to access Mail on my iPhone 3Gs and on the web using Safari to access Mail in my iCloud (Cannot load Mail). I've tried the password reset option proposed here following the steps exactly as described. The problem persists.
