ASCI attachment lost when sending mail by MAPI or CDO

ASCI attachment lost when sending mail by MAPI or CDO

In some cases mails send by a VB application using CDO or MAPI the ASCI attachment is lost or corrupt.
The thing is that the sender can see the mail in his sent items with the attachment but the recipient receives the mail without the attachment, or the ASCI file can't be used anymore.

In some cases this is because the winmail.dat file is send along with the message.

This is the Exchange client adding Rich text information after the ASCI file.

This can be prevented.

For more info seen


Exchange administrator can do this.

Go to Exchange System Manager. Open the Global settings container and select Internet Message Formats.

In the right pane click new domain.

Fill in the required fields. As the example below. Replace test and test.com with the appropriate domain where you want to send RTF files to.

If the value is set to Never, RTF information is never sent.
If the value is set to Always, RTF information is always sent, regardless of the recipient properties.

Hoe schakel ik het envelop icoontje in wanneer er nieuwe mail wordt ontvangen in Microsoft outlook

Met dank aan super collega Nico Nuytten

Klik op Opties in het menu Extra.

Klik op E-mailopties en vervolgens op Geavanceerde e-mailopties.

Zorg ervoor dat het pictogram van een envelop weergeven aan staat

Klik vervolgens op ok

klikt u met de rechtermuisknop op een vrije plaats in de system tray en kiest U Meldingen Aanpassen

Zorg ervoor dat Er zijn nieuwe nog niet geopende… staat op Altijd weergeven

Restart de Pc en wanneer er nu nieuwe mails binnenkomen, verschijnt nu een envelop met de melding Er zijn nieuwe nog niet geopende items
