Outlook Addin does not shutdown properly when BCM is used

[Cedric]

Hello,

We have many problems because Outlook doesn't shutdown properly.
We are using Outlook 2007 with BCM + Exchange 2007.

With the following addin (written in C# with Visual Studio 2008) , Outlook
2007 shut downs properly as expected.
As soon as the BCM addin is also activated, Outlook 2007 doesn't shutdown
any more.

Could you please fix this bug? Is there a workaround?

Thanks,
Cedric

Usually these kinds of problems are because a reference to an object
is not being released.

You appear to be doing the right thing in ThisAddIn_Shutdown setting
the namespace to null and calling garbage collection, which I
assume(?) will internally call Dispose on nameSpace.

I take it Outlook shut's down if your addin does not get the MAPI
namespace?

Hello,

Yes this is basically getting a reference & dereferencing the Mapi Namespace:

Startup:
nameSpace = this.Application.GetNamespace("MAPI");
Shutdown:

nameSpace = null;

Please not that this is exactly the same with this.Application.Session

Of course, our addins are much more complicated, but I could trace back the
problem to that single reference.

Again, what is unnerving is that it only fails when BCM is loaded.
It does not fail in Outlook 2007 without BCM, it shutdowns properly as it
should.
