Centralised administration of the Frequent Contacts Address book

[fredp1]

Hi,

How does an administrator specific entries in the Freq Contacts address book for all users?
GW 6.5

e.g We had a name setup for sending email to a help desk.
The help desk structure has changes so we created 2 new addresses but do not want users to send email to the old address. The old address is disabled, but a copy remains from in the Frequent contacts book. How do we delete the frequent address book for this name?
Thanks
Fred

Cheers
Fred
