How to view ost files in outlook?

[avilsben]

I need to view a mailbox (.ost file). I am running Exchange 2003 and Outlook 2003. The users' domain account has been deleted and the mailbox on the Exchange server has been deleted. I have tried to recover the mailbox through Exchange without success. I have a cached copy of the .ost file in the users' profile on a laptop, running Windows 2000, t the user used to use. When I try to log into the users' domain profile on the laptop I get denied because it can't authenticate with the domain controller. Giving me the error username, password and domain do not match up. I do not have the password of the user nor can I find her profile under Users and Passwords on the laptop. The profile physically exits under Documents and Settings\username.domain. I tried to use the net user command to change the users password and simply login to the users account with no success.
