How are you trying to copy the addresses? Are you beaming them, using import from one desktop to the other, or what? If you are doing this by exporting from her desktop and then importing to the T5 desktop, what file format are you using? The database formats on the T5 and Zire 72 desktops are different so, if you are exporting to an ABA format, that's probably causing the problem. You should export to CSV format and then import. You'll have to use the field matching dialog to get the correct fields matched up between the two formats.
