You may have to end up contacting customer care. Are you on a computer when you are signing into your
adobe account and resetting your password?
"Email address is already in use" message
If you ever signed up for anything at Adobe.com using your email address, you receive this message when trying to create an Acrobat.com account. If you get this message and you don't remember your password, you can request a new one here.
You don't need a new or separate account for Acrobat.com, but you do need to take the additional step of verifying your email address. Follow the instructions when you attempt to log in, and an email verification notice will be sent to the email address associated with your Adobe ID.
If you do not receive the email verification notice, check your junk mail folder as some email services and clients mark them as spam. If you still cannot receive the email, please contact Support.
Please use a different browser other than the one you are using on a computer such as 'firefox, chrome, internet explorer' etc
if you want to try to reset your password ***** before contact.
