Copy pre existing email into a new archive account?

[JBP]

Hello,

I am sure this has already been answered but I could not find the information anywhere.

I have just enabled A&D for some users that have been on our system for quite some time and it is working great. However it did not move all of the pre-existing email into the archive account.

I need to know how to gett all of the emails that are in the users account prior to the date archiving was turned on, into the archive account.

Thanks you for your assistance.
