Clash of Outlook 2010 folder Rules when using POP3 & Exchange accounts

Main email account iin Outlook 2010 is POP3 with 50+ rules for distributing email into folders. Attempted to set up a secondary account which is an Exchange account. No rules needed for this account; volume will b v low.

Rules set up for the POP3 account are being applied to both the POP3 and Exchange accounts. Exchange account is rejecting rules and declaring them invalid. From main email menu in Outlook, going to Rules and then Manage Rules and Alerts, I can see that the rules are being applied to both accounts. I cannot see how to get rid of the Exchange account in Manage Rules and Alert.

I have dropped the Exchange account till I can get advice on this, and will have to restart set up of Exchange account but hopefully with some guidance on how to avoid over zealous application of rules beyond the POP3 account for which they are intended. My Hotmail account is unaffected.

Thanks in advance

Have you tried using the "Sent to people or public group" option?
