Using Application wouldn't solve a problem of missing events, it just uses
the trusted Application object and is a good practice for all Outlook VBA
code.

You should not miss events when Outlook is updating the status bar and
waiting for a time between making a change and saving it should also not be
a factor. I'd probably comment out all my macro code and just write a debug
statement using Debug.Print to make sure the event handler was being called
first. Then after that got running I'd start in on why sometimes the event
was missed.

Hi Ken
Thanks for your answer.

I have removed “Dim myOlapp As New Outlook.Application” and replaced
myOlApp
with Application throughout. OK? The problem is still there.

I’m missing things when I click an appointment in my calendar, then move
the
start- or end-time and then click beside the appointment to save it. If
the
time between moving and clicking is less than 2 – 3 seconds, the
ChangeItem
event will not fire in about 5% of all attempts.
I think only one item is changed at one time and none of my macros are
running when the event should fire.

I have used a date in the past for testing and I get “This appointment
occurs in the past” in the bottom of the calendar. I think, but can’t
prove
it, that if I save my appointment during the time outlook is writing in
the
bottom of the calendar, then I will miss things?!?
