I sometimes surprise myself with the levels of utter noobishness I can sink to!
Everything was correctly setup but for the usernames.........I failed to realise that each e-mail account had a different username (I couldn't remember setting them up) Thats why only one addy was returning e-mails--the one with the correct username! Doh!
As soon as I changed each to the correct name, everything was fine...
I am even getting my Axim x61V to synchronise with outlook as well!
Anyhoo, thanks for your help SnoopZ
