Hi Helmut,

  I tried placing the syncButton.delete inside the active inspector's
close event, and while it had no effect on OLK2003 (this is good), it
has resulted in very strange behavior on OLK2002. For any given
session the behavior is good (new buttons are not added).

  However, when Outlook closes and then is opened again, various things
seem to happen:

  1) A new Sync button is added on the first email opened.
  2) Sometimes the Outlook session is closed down behind the email
opened. (?)
  3) I received a COM error one time (not readily reproducable) that
says that the synchButton could not be deleted.

  The flakiness leads me to believe there's a problem in the
surrounding code, let me explain the basic process and see if it makes
sense:

  AddIn.onConnect:
      Grab instance of the Outlook object.
  AddIn.OnStartUpComplete:
      Grab an instance of the Application Object's inspector.
      Add an event handler to the inspector to be fired when a
"NewInspectorEvent" happens.

  AddIn.NewInspectorEventHandler:
      Check inspector.currentItem. If it's a mail item, launch a new
'SynchMail' object.

  AddIn.Disconnect
      if the Inspector isn't null, Release it.
      if the Application Object isn't null, Release it.
      Garbage Collect

  SynchMail.constructor
      Get active mail item.
      Add event handler to active mail item.open

  SynchMail.activeMailItemOpenHandler
      Remove event
      grab the mail item's active inspector
      Add a close event handler to activeMailItem.
      Call addUI

  SynchMail.AddUI
      Create a button on the standard task bar
      Add event handler to the button

  SynchMail.HandleButtonPressed
      Do my functionality

  SynchMail.CloseEventHandler
      Remove the CloseEventHandler from the active inspectors events
      delete the button.
      release the active inspector
      release the active mail item

  In a little more testing I've discovered much to my chagrin that the
'outlook closing itself' issue happens on both OLK2003 and OLK2002 at
this point. I'm suspicious of my logic flow, but really am in the dark
about what I could be doing wrong.

  As an aside, do you know how to reset the toolbar on OLK2002? When I
am in a mail message (where all the spurrious synch buttons are), the
'add or remove buttons' menu items are both greyed out.

  Cheers,
  'cuke
