SYMPTOMS
When a Microsoft Exchange 2000 Server user sends a Simple Mail Transfer Protocol (SMTP) e-mail message with an attachment to a mail-enabled contact in the Global Address List, the mail-enabled contact may receive a Winmail.dat file attachment with the e-mail message instead of receiving the correct file attachment.



CAUSE
This issue may occur if the following conditions are true for the mail-enabled object on the Exchange computer:
 * The default message format is set to Rich Text Format (RTF).
 * The mAPIRecipient attribute is missing, is set to null, or is set to true.

Note This typically occurs if the mail-enabled contact is added by using a script.



RESOLUTION
To resolve this issue, change the settings in Active Directory Users and Computers so that the mail-enabled contact does not use RTF as the default message format. To do this, follow these steps:
 * 1) Open Active Directory Users and Computers. To do this, click Start, point to Programs, point to Administrative Tools, and then click Active Directory Users and Computers.
 * 2) Click the container where the mail-enabled contact is located.
 * 3) Right-click the mail-enabled contact in the right-pane, and then click Properties.
 * 4) Click the Exchange Advanced tab, and then click to clear the Use MAPI rich text format check box.
 * 5) Click Apply, and then click OK.
