Enhancements to the standard IBM Lotus Notes 6.5/7.0/8.x mail template.
Meeting invitations show up on calendar in DWA(iNotes) before users accept meetings. If the calendar is viewed from the Notes client everything looks fine.
Can you confirm this behaviour is not the same as in the original lotus template?
This is a new feature of Notes 6.5 DWA. The invites show up on the DWA calendar with an envelope icon. Once the user accepts the icon changes to the handshake.
