Hello Carolfromwaynesville,
Thanks for using Apple Communities.
For manage your AppleID, access appleid.apple.com and log in using your current info. The two-factor authentication may be needed to access the account. Once you're in, under the subject Apple ID choose edit, and type the new email address (hotmail) and choose "save".You must remember that your new email address must not be used for Apple at any other services. If so, you should call AppleCare and ask for help at erasing the hotmail address from the other Apple services
With regards,
Alefe ****
