How to back up and to restore Outlook Express data
Hope this helps.
I just created a second user in my Dell Dimension E-510 running XpHome wikth all updates. Reason: Could not get Maximizer to sync up with my server as User #1, so I created User #2. Now...How can I move or migrate or copy the entire Outlook Express data from user #1 to User #2 so that I don't have to log off, log on, each time??
