If the e-mail address was one provided by the company, then yes, the company does have the right to change the password.
I take it you did not use an e-mail client such as Thunderbird or Outlook?
That said, I'd suggest talking to the company and informing them that there are e-mails in that account that you need copies of. If you filed the e-mails into folders, you could tell them the folder names containing the e-mails you need. With luck, they have not been deleted.
A word to the wise: Never use a work e-mail account for anything not work related.
