Multiple Accounts for Evolution (IMAP and POP)

Recently, i got a new email account with a new provider (POP). So I tried to configure
and add this new account , so that Evolution handles both of them. I simply thought,
after configuration of this new account it would appear as a new account. But
this does not seem to work, it never appears. At every startup, Evolution asks me
for the password of this account, but after providing it, nothing happens.

How do I tell Evolution to work with 2 or more email accounts?
Thx
