I am trying to change my Apple ID email address. I’ve done everything I’m suppose to and it says address not available. So I signed in with the email address I want to use and it signs me in but takes me to the address I’m trying to change? WEIRD

Is the e-mail address you are trying to use associated with the current ID in any way, for example as a Notification email address or a Rescue e-mail address?

Apple ID email addresses.   

Apple hasn’t published any guidance for using an address again. Normally, if your e-mail address was associated with an ID in any way, for example as a Notification email address or a Rescue e-mail address, then it can't be reused with another Apple ID for approximately one year. I have also seen posts that stated Apple told them there was a 30 day waiting period before the address could be used again.  You will need to get another e-mail address to use as your Apple ID or you can try waiting 30 days to see if that works.
