Labnuke99 is correct that it does depend. However, I do agree that a T1 should be sufficient to accomodate your 20 users. I have done about a hundred bandwidth analysis for Exchange disaster recovery installations, replicating entire Exchange databases from a production location to a DR faciltity sometimes thousands of miles away and based on your description this should be fine and probably the minimum I would start with. If you find performance begins to slow you can always bump up to a 3mbit . Good luck.

Another thing to consider, maybe down the road, is WAN optimization, which increases WAN speeds without adding expensive bandwidth.
