We had customers sending in tickets without creating customer accounts for them. Thus, john@home.com would write an email, a ticket would be created and solved – over time, he’d have dozens of tickets, all of them successfully solved of course.

His customer number in the system would be john@home.com as he doesn't have a customer account. Now, we’re starting to use the web front end and for this aim we're creating customer accounts, and I thought that if I create an account for john@home.com he’d be able to login and see his former tickets. That’s not the case, unfortunately. I used his email address as customer number, but it’s not working (and of couse it's not working when I use a number as his customer number). I’m not even sure this is the way it should be done (i.e., usage of real customer numbers 1, 2, 3 etc.). How can we connect his new customer account with the tickets that were created for his email address in the past? Any help is greatly appreciated!
