My company uses Exchange 2003 and Google apps for email service. Google Apps is set up in dual delivery mode with the legacy server running as the primary server. We have a user on Google apps that when an invitation to an updated meeting is received, a message on the invitation tells the user that the invitation is out-of-date and the user is not given the option to accept or reject the invitation. When the user clicks on more details, the details are for the original meeting, not the updated meeting thus not allowing the user to have updated meetings on her Google apps calendar. This does not happen with all invitations. It happens sporadically and when invitations are received from both Gmail users and outlook users. Also, other users receiving the same meeting invitations are not having this issue. Can someone help or give insight as to how to resolve this issue?
