Having to cnstantly choose to overwrite local....

Every time I get a notification of an event from my wifes calendar and i choose to dismiss or dismiss all , I have to choose to overwrite local. How can I stop this?

Hi Michael this can occur while two email clients are running with the same account setup. After you dismiss a calendar popup, the other computer will receive this notification as change has occurred to an existing and synchronized event.

Thank you,
Paul.
