I have installed outlook alongside the McAfee toolbar and I have several email accounts to setup. With the help of outlook rules being set to direct inbound messages to a particular folder , Now at the time of McAfee toolbar scanning, I received as spam and also got the error message as follows… “Theaction cannot be performed in the current Outlook folder“If anyone know the solution please provide me as it will be a great help for me. Thank You.
