Hello, All I'm programming a bit of Visual Basic for Outlook 2000, and CDO is giving me some unexpected behavior. Any wizards out there who can enlighten me on the issues described below, please reply off-list to [email protected] MUCHAS GRACIAS! -Atomik Technologies: CDO, Outlook, Visual Basic 1) Preview Pane: Changes to CDO Message Text property are not reflected in the Outlook preview pane, even after executing the Update method on the CDO Message object and executing the Save method on the associated Outlook MailItem object, unless I manually switch to a different folder. 2) Save method: After executing the Update method on the CDO Message object with the Update method, executing the Outlook MailItem Save method causes the following error: "Run-time error '-1075576567 (bfe40109)': The messaging interface has returned an unknown error. If the problem persists, restart Outlook."
