Adding new contact from e-mail

Adding new contact from e-mail

Hello,
I have added a new contact from an e-mail using the "add contact" by clicking on the e-mail address in the e-mail and adding it.  It says it is saved, but when I go to the contacts, it is not there, so I try adding again but get an error message that it is already added.  How do I find this e-mail address in my contacts?
