The iCloud IMAP server “p99-imap.mail.me.com” rejected the password for user XXXX

I'm also recieving the password error message on my iMac but have no problem accessing the mail account via Safari, hopefully its a glitch and will naturally resolve itself?.

I changed the password for my AppleID thinking that would get me back in business. It did not. Restarting seems to help some people, going to try that next.

I find it comes and goes. The problem seems to be on my Mac, since my iPhone seems to be receiving mail just fine.

I changed my password, now I amnot sure what to type in. Nothing works. Do I have one password for .me and another for .mac?

Same problem here, but right now only with Mac Mail on my MBP. I seem to be getting mail fine on my iPad and Android -- for now.

As I mentioned previously - I'm fairly confident the problem is on the authenticating servers at "applid.apple.com".

Going there earlier directly from Safari produced variously:

Broken HTML

Server not found

and about 70% of the time a connection

Even when I got a connection subsequent pages deeper on the site may or may not load.

Since this is the address where mail is checking credentials iOS mail and client mail react slightly differently to the wait and/or bad return.

It may either be a load issue, or if this server bank also serves MobileMe, a configuration issue.

We can but wait...

I'm getting this error on all my OS X and iOS 5 computers and devices.

I even delete the account and tried to add it back on the MacPro and now it will not even add the account back and rejects due to the same error message.

I fixed mine by doing so important steps! (don't have Mail on your Mac open while doing this).

1. Open Mail (if it is still not working) and go to Mail's Preferences, Accounts. In the Accounts pane highlight the non-working iCloud. Then select DELETE IT (don't worry you will add it right back going through the steps.) Then quit the SMTP server list (making sure you deleted any iCloud reference). Then quit Mail.

2. Go to theiCloud web page and make sure you can log into it and use the email portion on the web site! This is import to procede!

3. If you can complete step one, proceed with this step. Open System Preferences->iCloud pane and sign OUT. Close System Preferences and open it right back up and go back to System Preferences->iCloud pane and sign back in with your Apple ID.

4. Open Mail. Then go to Mail's Preferences, Accounts pane. Then if the iCloud Account is gone click on the + sign and add the iCloud account back using the settings found at the Apple site iCloud: Mail Server information . Just make sure when using the when using the incoming name, use your APPLE ID that you signed in on the Apple iCloud web site !!!

Enjoy Apple's fix. As I said before on the incoming iCloud Mail setup use the SAME APPLE ID you can sign into the Apple iCloud site !

I just hope this fix works for all of you because it worked for me here on the East coast at 1130, Thursday October 13th.

same here in France.... password pb with email on icloud using mac mini iphone and ipad.

Moved this morning my mobile me account to icloud, it just worked fine until this afternoon.

Doesnt work for me. I can login to icloud.com but when I click on MAIL Iam getting a endless loading symbol.

Is this APPLE problem? If so, i will wait for thier fixing.

This works, I did it a bit different, I created a blah@bob.com to avoid the system forcing imap/smtp servers on me and manually put the information from http://support.apple.com/kb/HT4864 into the outgoing and incoming server info, saved it then went back and changed the stuff to my @mac.com email...working fine now...

I think satcomer's solution is more elegant.

Thanks!

2. Go to theiCloud web pageand make sure you can log into it and use the email portion on the web site! This is import to procede!

Did that, the iCloud email web-app stands there, white screen with a little cogwheel in the middle that just spins, and spins, and spins.....

This is the most royal FUBAR Apple has committed in a long time.

Same problem here. No iCloud mail on any device or app. Password error. Mail page @ iCloud.com spins and spins...

Same problem. iPhone mail works. Mac mail keeps rejecting password. iCloud site does not respond / times out. Even these support pages are slow to load. This is a serious failure by Apple.
