Why weren my Rules, Schedules, and Signatures imported from Entourage v.X?
They should have been imported. If they weren’t picked up, it is likely because the import terminated abnormally – most likely due to some database corruption. It’s a very good idea to do a Rebuild of your X identity, in X, before importing it into 2004. (Even more important if you’re coming directly from 2001 to do it there first.) See Tips on a good install (here).
