roaming profiles and exchange?

I have a firestation that has about 25 different users and only 6 computers. I am trying to create roaming profiles (which works) except for their email, which gives an error because it is looking for the ost files on the local machine, thoughts?

sbs 2003
all xp pro machines (older)

Could you tell us the exact error received?

The reason I ask is because at work, we use roaming profiles for a small group of users (about 15), and these users also use Exchange-based email (Outlook 2000 and 2003) and their email works fine. Not that I'm saying that this issue isn't possible, I just find it weird that this is happening (but then again, all sort of crazy things happen in the Microsoft world).

thanks buddy the problem was cached mode was on.
