Merging two contact folders from different mail accounts

[MoyoManny]

I support an administrative assistan who uses a Card Scan reader to import
business cards to her Outlook contacts. The issue is she is the admin of
another contacts folder and we need to get the contacts "synchronized"
between the two.

I do no we can do the drag n drop method, but there are a couple hundred
records so it will be time consuming. Is there an easier way to accomplish
this?

thank you in advance for your help.
