If you're running in Internet Mail Only Mode, no. If you're in Corporate or
Workgroup mode, yes, there is. You can check your mode by selecting About
Microsoft Outlook from the Help menu.
If you're not connecting to an Exchange Server or using any IMAP accounts,
you can change your mode to Internet Mail Only. Select Tools | Options |
Mail Services | Reconfigure Mail Support. You'll probably need your
Office/Outlook Cd handy for this.
Once finished, you can use profiles (similar to OE's Identities). Select
Start | Settings | Control Panel and open the Mail applet to access the
profile Wizard.
