I have had the setting selected in my lotus notes so that when I press
delete on an accept or decline for a meeting it would not delete them but
remove it from my inbox, update the calendar invite and record in the
meeting view of my calendar. A great system.
Yesterday I noticed that an acceptance in by trash, when I check it hadn't
updated in my calendar.
And the meeting below appear to have the same problem (but for lots of
people) where I know they have accepted but it hasn't updated.
