If you need a higher version of Outlook then Outlook 2000 you'll need to buy at least the upgrade version of that higher version of MS Office (XP, 2002, 2003). But Microsoft won't object if you buy the full version.
So: up to the shop and see what they have to offer you.
I don't have an opinion on IF you need a higher version of Outlook; in that respect I trust what you say. And I don't know at all what you mean with "each email needs its own outlook application". What's wrong with using multiple XP users each with it's own Outlook 2002 database and email-address. That's an identity at OS level, not at application (Outlook) level.
Hope this helps.
Hi I have a laptop with Microsft XP 2002. IN Miscrosift Outlook I need to have multiple emails "profiles" . Outlook 2000 is what I have. So how can I upgrade it to newer version that allows me to have profiles for different email addresses? Is there an upgarde or do I have to install a newer version etc..I own a nightclub so I have to many emails coming into one box, and this is my laptop so I do all my work on it and am quite mobile, each email I have needs its own outlook application if you know what I mean..thanks, i weent to microsft office but ofcourse, MS is no help.
