Send update to attendees not always working

[johnmarkham]

Hi,

When modifying an existing appointment in my calendar with a new attendee, most of the time I am not prompted with the dialog box: "Send updates only to added or removed attendees/Send updates to all attendees", instead the modification email is sent to all attendees...

I could not find any related bugs. Is this a known issue in Zimbra version 5.0.20.?

Thanks very much.
