I use the following format

OutlookItemEvents( theOutlookObject, true )


When RemoveConnection() is called, is there a way for me to get the current reference count on that object?

I'm looking for something similar to


int iRefCount=0xFFFFFFFF;
iRefCount = Marshal.ReleaseComObject( theOutlookObject);

Hello German,

This isn't possible if you call ADXOutlookItemEvents.ConnectTo(..., true). If you call ADXOutlookItemEvents.ConnectTo(..., false), you will be able to call Marshal.ReleaseComObject() and get the reference count.

Marshal.ReleaseComObject(...) never executes because ItemObj is always null after RemoveConnection().

Am I allowed to call Marshal.ReleaseComObject on ItemObj? 


    int _mailItemRefCount = -1;
    public int MailItemReferenceCount { get{ return _mailItemRefCount; } }

    if (_ItemEvents.IsConnected == true)
    {
    
        _ItemEvents.RemoveConnection();
        if (_ItemEvents.ItemObj != null) { _mailItemRefCount = Marshal.ReleaseComObject(_ItemEvents.ItemObj); }
        log.Debug(string.Format("MailItem Reference count: {0}", MailItemReferenceCount));
    }

Please ignore my last post. I forgot that you're not supposed to release Add-In-Express Objects.
