Outlook 2007



I have used data management to create a new personal pst file and set it as default.
The objective was to create a new empty pst file. All of the data in the old pst file is now in the new pst file.
I would prefer to keep the old contacts, calendar, etc. but have no e-mails to start the new pst file.
Is it safe to delete all of the -emails in the new pst file without destroying the e-mail data in the old pst file?

Thanks for the attention.

To put it simply, I wish to save the current pst file and start with a new empty pst file.
Any new pst file I create using Outlook transfers all the old data to the new file.
