Mac Forum / Applications / Outlook Express / October 2003

On Outlook (not outlook express) on Windows, there is a filed named
OUTLOOK.PST that contains Contacts and email data.  A person can just copy
this file to a CD for safe keeping, prior to doing anything risky with
outlook, for example, synchronizing a palm pilot for the first time ...

I need to know what the name and how to find the file that
keeps the e-mail messages on my MAC machine.

I'm working with Outlook Express 5.02 for Macintosh (OS 9.1).  Since
about a week, I can only receive mails but not send any.  The error msg I get is:
Can not send mail from outbox. Server can not find recipient.
relaying to <"recipient"> prohibited by administrator; error 5550
