ok, then go into outlook and click on tools options and click on mail delivery. Click on reconfigure mail support. Set it to corporate work group. then you will get that. The only thing is that I am not sure that you will still have the mail you have in there now.
The good news is that no you can have as many profiles as you want.
To configure the email now, you need to add a personal folder, outlook address book and configure an internet email service for each user. To do that, you right click the icon and go to properties... Then click show profiles. Add a new profile, start Outlook as that person and configure it under tools> services. Click add and add an internet email service and a personal folder.
