SSL VPN vs. IPSec

Hi,

I am preparing to purchase HW and SW to support remote access for a small group of dispersed employees. I'm familiar with IPSec VPN as an option, however several people have recommended that I look at SSL VPN instead. I'm unclear on the pros/cons.

Our requirements are:

- Access to one more more common intranet folders and documents
- Access from secure and non-secure environments (internet cafe, hotels, etc)

All of the clients are Windows-based.

Does SSL VPN provide a method by which we can access MS Exchange via native Outlook (instead of Outlook Web Access)?

Thanks!
