257824 OL2000: Differences Between Outlook and Outlook Express

SYMPTOMS

When you send a mail message containing another Outlook item, such as a Contact, Task, Mail message, or some combination of these items, the recipient is able to view these attachments normally. However if they send your original message to you or another recipient, the items arrive as a blank mail message.

CAUSE

Transport Neutral Encapsulation Format (TNEF) is required to assure that the Outlook form and its data sent as an attachment remain usable. TNEF is not activated in the mail message by default.

RESOLUTION

The Microsoft Outlook Rich Text Format (RTF) provides the necessary TNEF formatting to ensure that the attachment is intact.

To enable TNEF, use Microsoft Outlook RTF as the default sending message format for each mail message that will contain Outlook items as attachments. To do this, follow these steps:

  1. On the Tools menu, click Options.
  2. On the Mail Format tab, click Microsoft Outlook Rich Text in the "send in this message format" list, and click OK.
  3. On the File menu, point to New, and click Mail Message.
  4. On the File menu of the new message, click Properties. Ensure that "Send in Microsoft Outlook Rich Text Format" is checked, and click OK.
  5. On the Insert menu, click Item, select the items you wish to include as attachments, and click OK.
