I wanted to add a second account in Outlook 2003. So, I went to tools >> E-mail Accounts >> add a new e-mail account. I managed to connect to the second account. However, now I can't see my first account anywhere. The Inbox contains only mail from the second account that I just added. Is my first account lost? Is there a way to restore it because I really need these mails?
Adding a new account in Outlook does not delete the old account(i.e. including emails, tasks and calander) unless you did some mistake
So either you have created a new profile, which you can check it by accessing control panel > mail > profiles or you did removed the old account and added another one, for which you can look for the old .pst file
