Why can't I edit or delete contacts in the Global Address Book?

The Global Address List is a centralized directory managed by your organization's IT department. Only administrators or users who have been granted specific administrative permissions can add, edit, or remove entries from this directory.

Will my Global Address Book contacts stay with a Word document if I send it externally?

No. The Global Address Book belongs to the organization's Exchange or Microsoft 365 service. It does not travel with documents or files when they are moved or sent to a system outside of your organizational network.
