Removing double enties in Contacts

[Guest]

My wife moved fom Outlook Express to Outlook for her mail. She copied all
her address book over - it went in to Contacts. For some reason every item
is duplicated? Is there any way to delete duplicates other than doing so
manually?

I think MAPILab has an inexpensive utility for the job, which does seem
to arise from time to time.

Choose a view based on table layout,
then add the field "Created", then sort by Created,
all items imported will sorted based on date created,
all newly imported items are now separated.
