Is possible in Outlook 2007 to have 1 account with more email address
for send email?

Now, my mail server fetch messagge from 4 different pop3 account, and
put it into 1 imap account and Thunderbird access to this account,
and with identities I can send email with one of the 4 pop3 account
email like sender address

You can't have multiple addresses with a single mail account because there
is a one-to-one correspondence in Outlook between accounts and addresses.
Multiple POP accounts, however, will all feed into a single set of folders
and replying to any particular message will by default send using the
account with which the message was received. You can also manually choose
the sending account. Outlook has no such thing as identities.
