I am having issue on server rule on my Mac Outlook 2011. The rule shows (error) and I can no longer delete nor edit. I receive error message when I try to edit the rule:

"This rule is defined to run only in Outlook for Windows. To view or edit this rule, use Outlook for Windows."

Delete (minus) is grayed out. The fact that I never create any rules in Outlook for Windows confuse me when I see the above error message. This is for my company account and I only use Mac for all email activities since day 1. Any help is greatly appreciated.

Regards,

Tom
