Like others have said, you can turn off EVERYTHING in the iCloud account settings then click delete account. Then setup your iCloud again using your apple ID then turn on mail again and type new email.
Or if you want to make an email alias go to icloud.com/mail (on the computer only. Not i device) then click alias and. Create your alias
You change it through itunes store - it automatically changes icloud's email as well;
-click on itunes store
-the email address in the right hand corner has a drop down arrow, click on that and then click on account
-underneath "Apple ID Summary" you will see your information, including your email addresss.There is an edit button on the right side. click on that change your email and or password and continue.
to double check go to icloud.com and log in with the new email address you changed it to.
It worked for me
This is the perfect solution.
People trying to change the cloud account address need to realize that this is just a link to a server to save your device contentu.. The address is part of your iTunes identity and the email address therefore has to be correct in iTunes and linked with your apple ID. The devices will automatically have this address as your default cloud address.
That is why an incorrect cloud address cannot be changed, but the incorrect cloud account must be deleted to sever the link to the cloud server.
I got bored reading all 5 pages of responses, so my solution might already be posted. I started by going into iTunes and changing my email. That was easy. Then, on my computer I simply went to System Preferences (NOT iCloud), then Users & Groups under System, then clicked "Change" by the Apple ID (you'll need to use your computer password rather than your Apple ID password), then deleted my existing Apple ID and added my new one. I can't remember if I had to make the same change on my iPhone or if it automatically changed the id, but it was easy either way.
Let me know if this works for others.
Just to clarify... people are not trying to change the email address associated with their apple ID. They are trying to change the "@me.com" email address they originally were asked to create when setting up their iCloud mail. I for one, do not want to change the email address attached to my apple ID. I want to keep it the same. When I set up iCloud though, I wasn't sure what I was creating with the "@me.com" extension and so I put in random letters. I'm now stuck with that as my default "@me.com" email address and have to creat aliases. It appears that when I send emails (from my phone or my iMac or my macbook) that go via the iCloud email address, no matter what alias I send them from they are still coming from the original "@me.com" and not from the alias.
If anyone knows how to change your "@me.com" email address once it's been created WITHOUT changing your appleID, that's the real question here...
hehe! Found a simple solution: when configuring iCloud on the iPhone, at the Account field, instead of the Apple ID, I wrote the @me.com email address that I wanted to use. And that's it.
So you have to delete your iCloud account from the iPhone, select to keep the information on phone, or whatever, then create it back with the @me.com email you want to use.
Also, because this @me.com email came from mobileMe, I now have 25 GB of storage (20 mobileMe + 5 GB iCloud); so I really needed to enter this address in the iCloud setup.
If I'm a little ambiguous, lemme know and I'll post again, with steps.. I just woke up. )
I've figured it out.. Go to iTunes and under Store go to View Your Account and under Account Information - Apple ID: (your login email address appears) go into edit. There you will see the email address you are looking to change even though it does not appear on the main page. Good luck!
I have the same issue. I was a MobileMe customer with a me.com address before iCloud came out. Once iCloud was released, I was able to convert my iMac and MacBook Pro with no problems. However, my iPhone and iPad gave me the message that that e-mail address was already in use. (Well, yeah, it's in use by me and I want to connect it to this iCloud account.) I never found a way so to do an endrun and come back to the e-mail issue later, I dreamed up an e-mail address. Now my iOS devices use iCloud attached to that dummy e-mail. My Book and iMac are using the correct account with the correct e-mail. There has GOT to be a way to fix this.
For the record, I've tried deleting the iCloud account on the iOS devices. As one user noted though, this is merely breaking the connection. The problem that he/she alluded to but didn't address was that once the connection to that iCloud account is re-established, it is re-established with the same old useless e-mail address.
I just had to do this on my husbands iPad. His iPad kept saying his password was invald when he went to do app updates. I reset his password then it gave me the same error. I found his usernames for the Apple account and the iCloud account did not match. I deleted his iCloud account and it let me change his username to match his Apple account and this seemed to work. So I think you need to have matching ID's on the iPad or iPhone.
I solved the issue in the following way
First thing to realise is that you iCloud ID does not actualy need to be the same than your apple ID
So if you apple ID is email@example.com and you had firstname.lastname@example.org (typed incorrectly) as your original assosiated id but wanted email@example.com then go to ipad iCould and delete the account under iCloud as explained in posts above
then use firstname.lastname@example.org for all your store ID's on all devices so everyone in the family can get the same content at one purchase price
Secondly go to https://appleid.apple.com/cgi-bin/WebObjects/MyAppleId.woa/19/wo/TS2zCayGY4ZI4K4 Sy5Snz0/188.8.131.52.1.0.8 log in using email@example.com and create a second e-mail associated with this account, e.g. firstname.lastname@example.org, now verify it by logging into https://www.icloud.com/ and looking at the email sent to you
when that is done use email@example.com on your ipad, iphone and all your devices as your iCloud ID, in that way all your devices will be synced with your iCloud
hope that helps!
