Harmon.ie error when upload file -

After completing Harmo.ie for Outlook 2010, I tried to upload a file to a custom document library. . For information, the document library uses the custom content type and has the item receiver attached (item-added and item updates). For some time, harmon.ie displays an error, which states "File can not be uploaded to the selected library."

After debugging, there was an error before the item receiver. Does anyone know about this issue? I like this in our ULS logs and I bug but no luck !!

Here try to isolate the stack trace of harmo.ie:

Run Fiddler sent harmon.ie for SharePoint request To find out - you can give some details of the details. Also try the same operation against a library, which does not have any event handler.
