Hi Community, thanks for your help and support. I'm using TB V102.2.1 and am trying to drag an existing mailing list from one address book to another address book (in the same TB on the same PC). TB shows the "you can't do that" icon when I try to drop on to a different address book. Google searches tell me that drag and drop is the way to do this, but it isn't happening. I'm opening the address book that has the mailing list, highlighting the mailing list in the addresses list in the right panel and then dragging it to the new address book name in the left panel, but the "can't do" icon is displayed. The address list has several hundred entries that already exist in the new address book, so recreating the list will be painfull. Is it possible to move mailing lists between address books?
