For anyone that could encounter the same issue, here's what resolved the
problem in my case.
I have a private variable of type Explorer in the ExplorerWrapper class to
keep a reference to the Outlook Explorer object. In the Close event of the
Explorer I was assigning null to the Explorer variable, but this seems to not
have been enough. I added Marshal.FinalReleaseComObject(this.explorer), and
now Outlook is successfully shutting down.

FWIW I haven't had any problems with Outlook 2003, although the timing of
things in the template was adjusted for Outlook 2007.

A lot of work was done by MS for Outlook 2007 to fix the OnDisconnection()
not firing bug, it's possible things aren't optimized for 2003 in the
published template. I use a highly modified version of that template myself
for my own code.

Hi,

I am developing a C# COM add-in for Outlook 2003 and 2007.
Recently the need for supporting multiple Outlook explorers arised and I
am
currently implementing that. I used Ken Slovak's Outlook project
CSAddinTemplate as a sample - many thanks for the great template and all
the
guidance in developing COM add-ins for Office :-).
All is working fine for Outlook 2007, but in Outlook 2003 (it's SP3) when
I
start multiple explorers and then close them one by one, Outlook process
won't shutdown (OnDisconnection does not even get called). If I only have
one
Outlook explorer, the process exits nicely.
I thought I had forgotten to release any references to Outlook objects, so
I
disabled my add-in from the registry and left only the CSAddinTemplate to
load - this again led Outlook to not shut down. If I disable all add-ins,
Outlook closes without any issues. Also if I use File-Exit, and not the X
button, Outlook shuts down nicely, no matter if I have add-ins loaded and
how
many explorers are opened.

Have you ever encountered such issues with Outlook 2003 - is it a bug or
do
I need to re-check the code for unreleased references?
Many thanks for all ideas and comments,
Teodora Gancheva
