You're right Sergey, it does report on OLE. That should do the trick.

>Use AERROR() function.

>>Hi,

>>I'm using the Mapi Controls and the composition and sending of emails works great using Outlook Express. I bring up the email form for review prior to sending. However, using Outlook 2000 as the default mail client, it errors with an error code of 1429 when issuing the Send() method. It doesn't bomb my program, but logs the error and keeps going. Is there any way to get a text message from this control to get more details, or does anything know what is going on with this? The OleClass is MSMAPI.MAPIMessages.1.
