Mail stopped working for iCloud

Same problem here -- mail on iCloud has been working fine, including earlier today. Now, nothing!

I'm getting the same error message for my account.

"The MobileMe IMAP server “imap.mail.me.com” rejected the password for user."

Just happened for me, but I'll let it go for now to see if it resolves itself.

First yesterdays obvious plishing message to my @ me.com address that got through and now this.

I get the same message, but onlywhen tryomg to email from my phone. Works fine on my computer using the Mail app...

Just checked and the issue has been resolved without my input.

Same issue and timing but my account still isn't working.

I'm experiencing the same issue. Last night (Tuesday 1/21) when this was happening too, I called AppleCare, and the representative said that it was "a known issue" in the system that was being addressed. Then, as now, the System Status page (www.apple.com/support/systemstatus) indicated that all systems, including iCloud, were "Normal".

When I got up this morning Mail was again working fine without any authentication prompts, and it worked fine all day until this evening. Hopefully Apple is on it.

Having same issue, but I have been unable to get iCloud working again for Mail (4.6) on my Snow Leopard (OS X 10.6.8) - getting asked repeatedly to enter my iCloud password because the server has rejected it. Plus, I have tried deleting and re-entering the iCloud server information in Mail's Preferences ->Accounts section.

Feel like I have been orphaned by Apple, and I hadn't heard about any fantastic improvements to iCloud that whatever patch they applied was supposed to give Lion/Mountain Lion/Mavericks Mac users... In fact, until I started doing searching and found this and another couple of topics in the Apple Support Communities, I hadn't heard at all about this 'gotcha'.

Some very simple workarounds and other comments. I apologize for such a back to basics post.

The last post is 6 days old and I still have a problem.

I noticed the same problems with my iCloud mailbox using Mail 4.6 and OSX 10.6.8, it simply stopped working about a week ago and I can get it partially/sometimes working for a while by fiddling server settings. Changing your settings is a waste of time - this is Apple's problem to address. Making these changes just makes you feel like you're doing something helpful while they fix whatever is really broken.

If you are completely locked out of using your mail then the following 2 suggestions will get past that.

1. Use a browser to get to icloud.com, login, and select Mail. You should now have complete access to email.

2. If you use an ios device then you'll probably already have your email on it. If not, then set up your iCloud account in your iPhone/iPad/iPod mail program. Again this will give you "complete" access to your email.

I put complete in quotes since you obviously cannot easily transfer to/from Mac applications from your phone.

I have been trying for 5 weeks to get mail working on 10.6.8. I have tried every server setting I know and nothing has helped. Mail program is useless to me now that iCoud address is my main address. It's annoying to have to go to iCloud online to see emails. It worked for years and all of a sudden it stopped. Crap!
