another BIS BES question

I'm currently using BIS for 5 different email addresses (different domains). If I use an Exchange Hosting service for one of the emails so I can wirelessly sync my Outlook contacts and calendar, how do I get the other 4 emails?

I will switch my Verizon service form BIS to BES. My question is, do I still use BIS to get the other 4 emails?

Thanks, Dan

The same way you are right now. BIS is included with BES.

Thanks, That's what I thought. I just couldn't find it anywhere.

I'm going to do that. I like the idea of everything being in sync all the time.
