In my iCloud Mail 'Accounts' tab, the iCloud IMAP email address that's listed is an old address that is not used anymore and I'd like to change it to a current address. Also, it is not my Apple ID which is OK with me. However, the iCloud IMAP email address displayed in the MacMail app (under Preferences>Accounts) shows the correct address, which is an iCloud alias that's properly listed under 'alternate' in iCloud Mail 'Accounts'. My question: Can I update the IMAP email address in iCloud Mail and how could that be done, or would I have to delete the entire account and start over? Thanks in advance!
