All Outlook objects are marked as apartment threaded, hence thay must be
marshalled to the thread used to retrieve them.
Does the crash occur while one of your secondary threads is still running?
Do you trap Application.Quit event in Outlook and wait for your threads to
finish before you let Outlook proceed with the shutdown?

Hi Dmitry

Thanks for your reply.
In these threads we are searching the Outlook data files using WDS and
showing the search results in a folder home page .

There is no particular method that seems to be crashing.
This crash generally occurs when Outlook is closed.

Another query I had was : Is Outlook Object Model 2007 thread
safe????

Thanks in advance.

Regards

Hi

We are using OOM 2007, VSTO SE to createOutlook2007 addin.

We observed that after adding threads to our addin,Outlooksometimes
crashes.
Is OOM 2007 threadsafe?

We have passed ThisAddin.Application object in all the threads that
have been created.
Can this be the reason for the crash?
