Update: Outlook 2003 SP1 runs rules after junk e-mail filter. Update your installation if you haven't already.
If you use Outlook 2003 and have multiple POP3 accounts you may use Rules to move the messages to their own folders. However, when you use rules to move message, the new Junk Email filter doesn't remove the junk mail from those accounts.
To avoid this problem, use rules to set flags on each account so you can see at a glance which messages are from which account. You can use the For Follow Up search folder to see the messages grouped by flag color.
Or create a search folder for each account. Create a Custom search folder and used the Advanced tab on the criteria to filter by E-mail account. Enter the display name of the account, as seen in Send/Receive.
A third option is to create views for each account, using Filter's Advanced tab.
Using an older version of Outlook? While you don't have the junk filtering problem or search folders, you can create custom views or an Advanced Find to view email by accounts.
