ok, i manage to get as far as:

"You can have one or more .pst files, but new messages can only be delivered
to one file.

Now that your old items are available in Outlook, you need to tell Outlook
which data file is your primary data file and that all new items should go to
the Inbox in that .pst file. The file or mailbox to which your new messages
are delivered is called the default delivery location.

1. On the Tools menu, click E-mail Accounts.

THIS OPTION IS NOT SHOWING UP ON MY SCREEN.
