I expect that this has already been explained, but I can't find the solution so perhaps someone could help. I have a Windows SBS 2003 network. My Exchange mailbox stores all my email, but I have individual Outlook clients on various PCs (running Windows XP) pick up email from several POP accounts. I should perhaps have Exchange itself do the mail collection, but I find it convenient this way, with the clients doing the POPing (there are only a few) and it works fine; all the mail gets stored to my Exchange mailbox and also local .ost files on several PC's in the network (including a laptop often not connected to the domain). Everything syncs up nicely.
Here's the problem: I've just started experimenting with Office 2010. Setting up Outlook to work with Exchange was easy. However, when I set up a POP account, I no longer have the option to store incoming messages in my Exchange mailbox: Outlook insists I use a .pst file. How do I make all incoming messages get stored in Exchange? I tried pointing Outlook at the local .ost file but it wouldn't have it.
