I’m also interested in sharing Outlook Express on more than one computer – usually because one of the kids are on the ‘better’ computer when I need to use it!
These are two possible solutions I have come across, although I have yet to decide which one to use:
1. Go to Tools > Options > Maintenance and then change the location of the Message Store. (I would imagine that this solution requires the computer which holds the Message Store to be switched on also).
2. Set up each machine to leave mail on the server – one computer should be set to be used as the master in order to remove the messages from your ISP after a number of days. (Not too sure about the suitability of this method for my own use).
Would be interested to know if there is a solution which allows better sharing.
