I have 2 PC's with Office 2003 Pro.

I want to install the Office 2007 Beta on one of the PC's, at least
the MS Outlook 2007 module, and I want to install THAT with the
Business Contact Manager 2007.

Will I be able to safely copy my data, i.e. my .PST files back & forth
over the coming months between the PC running Outlook 2003 WITHOUT BCM
and the one running Outlook 2007 WITH Business Contact Manager?

I mean is there any incompatibility between the data files used by
Office 2007 and Office 2003?

I know that the Business Contact Manager stores its data in MSDE (SQL
Server), but is that separate from the Contacts, Emails, Calendar Data
in Outlook?
