I have a problem with my Evernote account regarding my email address. My account was created with my old university email address, which is now no longer in use (i.e. it's been deactivated). Now, when I try to sign in to change my Evernote account, it says I need to change my password for security reasons, and sends a link to do so to my old email address, which I can't access. Any ideas how I can resolve this issue so that I can update my email address on the account? Thanks in advance
