SYMPTOMS
If you attempt to open an Adobe Acrobat (PDF) file attachment that you received in a Microsoft Outlook 98 mail message, you may receive the following Acrobat Reader error message:

There was an error opening this document. File does not begin with '%PDF-'

This error occurs even if you have the Acrobat Reader installed on your computer.



CAUSE
The attached file is not in Acrobat PDF format. The Acrobat Reader expects the first characters of a valid PDF file to contain the following text string: %PDF- If the sender used an attachment encoding method that is not recognized by Outlook, such as BinHex, the file string begins with: (This file must be converted with BinHex 4.0) To determine if the sender used BinHex encoding, follow the steps in the More Information section below.



RESOLUTION
Have the sender change their mail attachment encoding method from BinHex to UUencode or Multipurpose Internet Mail Extensions (MIME) before sending the e-mail message with the attachment. BinHex encoding is a common format used by Macintosh mail systems and is also available with the Eudora Pro mail program. Consult the documentation for your particular e-mail program on how to set the encoding format.

Some Internet Service Providers (ISP) do not support receiving MIME encoded attachments. If this is the case for your ISP, the attachment may appear in the body of the E-mail message as encoded text. If you have this symptom, you can only receive UUencoded e-mail attachments.



To Determine the Attachment Format
Use these steps to determine if your file attachment is in BinHex format or in Acrobat Reader PDF format:  Drag the file attachment to the Windows Desktop. Using your right mouse button click the file and from the context-sensitive menu click Rename. Type Test.txt as the new file name and press ENTER. Click Yes to a prompt about the file becoming unusable if you change the file extension. Double-click Test.txt to open the file in NotePad.</li>  If the file is in BinHex format, the first line starts with: <pre class="fixed_text">(This file must be converted with BinHex 4.0) If the file is in Acrobat PDF format, the first line starts with: <pre class="fixed_text">%PDF- </li></ol>
