We are currently using Office 2003 in an exchange environment.
I am supporting a User is having a problem.

Person A has shared her contacts.
Person B is adding Person A's contacts to her outlook.

Previously when person B was composing a new email she was able to click New
click on "To" (or CC or BCC) and the in the drop down list on the right
default name is "Global Address List" person B would see person A's addresses
in the list.

now typically if you want to add your own address book to that drop down
list you would right button click on your contact - "properties" - "outlook
Address Book" tab and then tick "Show This folder as an email address book"

However when you follow the same steps on the shared contact the tab is not
available. I have tried numerous methods to try and fix this but with no
prevail.

If any one has any possible solutions it would be much appreciated.
