Hi Brian,
Thanks for the reply.
But -
I am SURE I jad only one .pst file (and one "Personal Folders" node
respectively) in my Outlook 2003,
and it served all my email account -
1. gmail account (I think it was IMAP, i am not sure)
2. exchange account (connecting to the exchange server in my office)
3. pop3 account
So, in my experience, the scenario in Outlook 2007 is new.

BTW,
How can I subscribe to get email notifications specifically to this
post?

Best,
Guy.
