Background: I have a home network with 4 PC's. We have five people in the household - each with their own e-mail account, and an additional one I keep for subscriptions (mostly spam). I recently purchased an HP NAS server which has worked great for sharing media files and personal documents (it also works as a print server - great device!). We have the newest version of Outlook (2007) as our PC's are new. Problem: The problem focuses around Outlook and our e-mail which seems to be hard to access. If I am on my laptop, I can only check 'new' messages via web-mail. Once it's downloaded into Outlook and 'cleaned' off of the mail server, I can no longer view my messages. I was wondering if there was a way to keep the Outlook 'datafile' on the NAS server and use Outlook as a 'client' to view the datafile. Wouldn't this allow me to access my Outlook via the laptop or the PC? I asked Microsoft support and they told me to purchase Exchange which I think is much more than we need for our 5 home users (all family members). Does anybody have any thoughts on how I might be able to have a mini exchange server or 'Outlook server'? I appreciate any thoughts and/or advice!
