Upgrade Outlook

[Please Help]

I'm on 2000 Outlook, do I need 2003 then to 2007 or can I go direct to 2007?
Where do I get an upgrade, I have been to four stores who state they are no
longer carring the upgrade version..

Direct to 2007
There is no upgrade version, for outlook alone, there is an upgrade for
Office, which depending on version of Office includes Outlook
Amazon sells Outlook on its own
If you go from Outlook 2000 to OL2007 there are some other hoops
reccomended, but that can be covered once you have your new version
Broadly, you would be advised to set up a new outlook profile with new data
file, and add your accounts.
