I made a huge mistake....

In restoring my .pst files I attached to the incorrect one and now i have a
lot of information in the incorrect one that I need to have moved to the
correct one. Providing I even know what the correct one is...then there are
emails still on the email server that need to be downloaded also.

Can someone please walk me through what I need to do to clean up this
herendous mess! Please?

Thank you
