Hello, we want Outlook 2003 to show context menus for certein emails with attachments. Like "Archive attachments...". Currently we use VSTO with VS2005 and add custom actions to the Outlook.MailItem if the selection event is fired. This custom action is permanently stored inside the mailitem in an exchange storage. But we also have EventSinks on the Exchange2003 side. Is it possible to attach the custom action to all mail messages with attachments within Exchange 2003? If a user calls this context menu, the action code would be performed from client side like it is now. Is it possible to modify the messages from within Exchange 2003? Best regards Michael M.
