Can not change apple ID to an icloud email account.
We are changing providers and so I needed to setup some icloud emaiI accounts for me and my wife. Then I changed to apple id to the new accounts. This worked fine for my new account, however the one for my wife is not accepted. The following message appears
Apple ID error:
This email address cannot be used as an Apple ID at this time.
I don't know why the icloud email account is not accepted and I don't find any options for delete the icloud email account for my wife and selecting another one.
Any ideas?
