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

Check things again and then if you still have problems post here, and I'll
see what's going on.

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.

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.
