Install OE on both machines, the downloaded mail will then be downloaded onto the machine you were using when you downloaded it. I'm not aware that you can set up share permisissions on your inbox, unless you store mail in a shared folder elswhere on your network.
I'm sure there is an OE expert on here who can help.
I don't think you can share the inbox but you can set Outlook Express so that the emails can be downloaded to both PCs. Open Outlook Express and go to Tools, Accounts, Mail tab. Highlight the account then click the Properties button. Click the Advanced tab then tick 'Leave a copy of messages on server'. Set your preferrence for when messages will be removed then click OK. Do the same on the other PC and you are setup to receive all messages on both PCs.
You might be able to use a synchronisation program to keep mailboxes in multiple computers synchronised. I have done it with Outlook (not Outlook Express), which is simple with a single .PST file, and with Eudora and Mozilla Thunderbird where you can select the storage location for mailbox files. I haven't actually tried it with the Outlook Express .DBX files as I don't use the program.
