A family of Microsoft word processing software products for creating web, email, and print documents.
Custom caption labels are stored in the Normal template (not the document template), and there is no way around this. They do not (cannot) travel with the document. Each user who works with the document will have to create these labels, and they must be precisely the same for each user for the cross-references to work. The good news is that existing cross-references will work once the custom labels have been created.
