I wanted to move a Outlook express account from my old machine to a new one.
The new one contains Outlook and Outlook express.

OL and OE are both mail clients but they are very different from each
other described in many places such as askleo. OL is a MAPI client, OE
is not.

How do Outlook, Outlook Express, and Outlook.com relate?

You will have to configure XP to have only one of them for your default
mail client on a system which has both.

If I creat an account on it it creates an .PST file.

A .pst is used by systems with OL; systems with only OE don't need a
..pst file. The .pst is used by windows messaging, MS exchange, & OL.
Not OE.

How do you plan to use OE and OL on the new system? OE is a popular way
to use newsgroups as you have posted here. If you 'need' OL for some
particular mail server, then you might use both.

MS has its own explanation for how to handle the dilemma of having both
OL and OE installed in kb2419492.

https://support.microsoft.com/en-us/kb/2419492 -"If you have both
Outlook and Outlook Express installed, you will have to choose one or
the other for the default client for e-mail, newsgroups and contact list."
