Hello NG I have developet an application that takes an Outlook mailitem from any given folder an save it to any given location as a MSG file. User can deside to include all or several attachments within the MSG file. Now if the mailitem is NOT shown in the Outlook reading pane or in any Outlook form all works just fine. Lets say that a mailitem holds 3 attachments a1, a2 and a3 and the user wants to include only attachment a1, and the mailitem i shown in Outlook reading pane or any Outlook form. Then the application makes the MSG file, now this strange thing happens: the attachments a2 and a3 is no longer within the mailitem any more. Does Outlook makes an mailitem "ready" for updates when shown in reading pane? and furthermore can I do something to prevent this to happen. Kind regards Johnny E. Jensen
