Error when trying to add a contact to my Contacts folder

[Louie]

In OL 2003, I am trying to add a person from our Global Address List to my
Contacts folder but get the following error:

"Some names could not be added to Contacts. The action could not be
completed."

I get this error when I right-click on a name in the GAL and select "Add to
Contacts".

Any help would be greatly appreciated! Thanks.
