I'm not new to Outlook, but I am new to Exchange Server.  I've used Outlook
independently for many years, and now our office is in initial planning
stages to implement Outlook 2003 system-wide using an Exchange Server.  
Previously, all my data was kept in .pst files on my PC.  I understand that
the data is now kept remotely with Exchange Server.

Ideally, I'd like to keep two separate files, one for personal data and one
for business data.  I'd like to continue to syncronize (ActiveSync via USB)
only the data in my personal .pst file with my PDA.  That would contain my
calendar, tasks, and contacts.

The business data on the Exchange Server would consist of official data
including all email and my public calendar.  I figure that I could always
drag and drop appointments or email to my personal .pst file if I want to
synchronize them on my PDA.

So, there appears to be a conflict:  I want to use my personal .pst file as
the default file so it is chosen for synchronization with the PDA.  But, I
sense that the exchange server needs to be the default file in order to
receive email and allow access for the public calendar.  Is my assumption
correct?  Or is there a way to set up Outlook to do both.  I know that
ActiveSync can only synchronize a single calendar.  Any help would be
appreciated.
