Using Outlook 2003 on Exchange Server 5.5

[Jun]

Hello,

I am using Outlook 2003 on Windows XP SP1 (updated) and I
am connecting to Exchange Server 5.5 SP3 (running on NT4).

There is some issue I saw on connection, is there some
way that I can used my Outlook 2003 connecting on
Exchange 5.5?

If not, can I install Outlook XP and remove Outlook 2003
without affecting the other component on Office 2003?

Thanks in advance.
