One of out customer installed multiple add-ins.
Our older version worked on his machine but not the newer version.
Disable or remove all other add-ins from Outlook add-in manager, re-enable
or reinstall our add-in won't work.
Reinstall Outlook won't work.
Add VSTO environmental variable does not help, not showing or logging
anything.
The loadstatus of registry key is the OK value 3 before uninstall and after
reinstall our add-in.
Other machines have no problem.

Any thoughts?

No way for us to know what's going on. You need to use managed code
debugging and Fusion logging to see what's going on, assuming that your
addin is failing to load. If it is loading then you need to run in debug
mode and add lots of error logging to see where things fail.

Assuming the addin just fails to load at all, see

for information on troubleshooting addin load failures with managed code.

The add-in did not load at all. There is logging as the very 1st statemnt in
startup event handler. Nothing logged.

We'll try the new tips. Thanks Ken.

The add-in was in the Disabled Items list. After enable it, the add-in was
loaded and the menu appeared. But now email won't go out. They stay in
Outbox forever.

I remember someone had the same email problem and asked for help a while ago
but I could not retrive the mail.It was gone.

Usually if an addin is disabled that way it means you have unhandled
exceptions, a cardinal sin for addins. Or that you aren't using a shim to
get your own AppDomain for the addin and some other code in that same
AppDomain is crashing Outlook or has unhandled exceptions.

If it remains in Outbox are you messing with the items after they're sent,
or accessing them in Outbox, or not releasing the object references?

The problem of mail not going out only occurs on Outlook 2007, not 2003.

I believe it is caused by the interception of Explorer's SelectionChange
event.

//class level variable to hold event handler
private Outlook.Explorer explorer = null;

private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
explorer = this.Application.ActiveExplorer();
explorer.SelectionChange += new
Outlook.ExplorerEvents_10_SelectionChangeEventHand ler(ThisAddIn_SelectionChanged);
}

private void ThisAddIn_SelectionChanged()
{
// only handle appointments, nothing else
if (explorer.Selection.Count 0 && explorer.Selection[1] is
Outlook.AppointmentItem)
{
...
}
}

Once a new mail is created, Outlook put it into Outbox folder and fires 3
SelectionChange events.

I know JavaScript DOM event bubble up and vaguely remember one article
mentioned about passing Outlook event out of event handler. How do I pass
the Explorer's SelectionChange event back to Outlook, so Outlook can handle
it as usual?
