Use commandline switches( A command-line switch is the addition of a forward slash followed by the command name and any parameters.), use  
/cleansniff     
Overrides the programmatic lockout that determines which of your computers (when you run Outlook at the same time) processes meeting items. The lockout process helps prevent duplicate reminder messages. This switch clears the lockout on the computer it is used. This enables Outlook to process meeting items.
