It doesn't say anywhere on the DynoPlex web site, but on another BB forum it says the eOffice Professional Edition v4.1.021 is not compatable with the 8830. Maybe someone else will chime in, but I don't think it will work.
eOffice is compatible with 8830 except for one issue - in certain configurations you cannot copy files through USB using eFile Desktop. This is due to some USB API quicks on 8830, we're investigating with RIM.
