Emails stay in Outbox forever once addin is loaded

[Jason]

The problem only occurs when user click the Outbox folder, then send an
Email. No problem if the folder is not selected.

The problem happens on Outlook 2007 and 2003. Not every computer will have
the problem.

The problem is caused by the interception of explorer.SelectionChange, whose
sole purpose is to catches the EntryIDs of the appointments selected for
deletion.

In Outlook 2007, the problem can be avoided by replacing
explorer.SelectionChange with BeforeItemMove event.

What is the feasible solution for 2003?

Hi Jason,

You are not alone. I have seen this issue multiple times with Outlook 2003.
I believe this is an Outlook problem of some sort. I think it is a race
condition and has something to do with the view table.

In fact with some of our add-ins that are message intensive I have disabled
(low level hook) from selecting the outbox during message processing.

Thanks Tom. I agre that could be the last resort. Right now we just leave
the option open. Our customers pay for the service. Internal users are much
easier to deal with.

The problem of Email won't go out appears in one VM for Outlook 2007. No
problem in dev machine since we replaced the ActiveExplorer.SelectionChange
with BeforeItemMove event. Now the suspect is
Application.Inspectors.NewInspector event. What we really need is the
calendar item open event (or better, the Read event to handle in place
input). Is there any way to catch the calendar item Open/Read event without
intercepting the NewInspector event? Please advise how to.
