Upgrading from outlook 2003 and 2007 to office 365 small business outlook

We just bought office 365 small business thinking I can easily set up outlook as we did in outlook 2007.

That is creating an account using POP3 and SMTP for every individual.

I just started watching a video of how to set up the out look in office 365 and it does not make any sense to add all 30 mail boxes set up in Network solutions and work around our domain names and all sort of unnecessary complicated step to use this on line office.

Can we just set it up the way we did in outlook 2007 without having to deal with all parties involved?
