Changing pst. files to main file

[Dave]

Hi,

I have an existing .pst file for personal use. I have
added an Exchange account to my PC using rpc over https.
Now I have 2 sets of folders, personal and Exchange. I
want to change and make the Exchange folders the primary
folder for Outlook 2003.

I have 2 settings in mail in my control panel, Exchange
and Outlook. When I try to make Exchange the profile, it
has problems and tells me to I am not connected to
Exchange server (I am connected). The Exchange profile
does not seem to be affiliated to any account.

Help.

Dave
