Data Files Merge in Outlook 2007

[Raas]

I want to merge two datafiles into one. Of course, both are .pst files and
on the same computer.

How do I do this without creating duplicates or deleting any e-mails from
the files?

Thanks.

Start with a backup of both files. Then you can drag & drop your
folders/items from 1 pst-file to the other.

If you have the same items stored in both pst-files, you'll need a
duplicates remover.
