This article was previously published under Q178241 SYMPTOMS
When you send an Adobe version 1.2 Portable Document Format (PDF) file
(created by Adobe 3.0 Writer) as an attachment with an Exchange client, the
attachment is encoded as "quoted printable." However, a version 1.1 PDF
file will get encoded as "base64."
PDF files (Adobe Portable Document Format) are the format in which
documents are saved for viewing and transfer by Acrobat Reader and Acrobat
Exchange for Macintosh and Windows. The encoding from the Microsoft
Exchange client is determined based on the first 4 KB content of the
attachment. Adobe changed the format between versions 1.1 and 1.2 PDF
files. The 1.1 PDF version is based on Base64 encoding; the version 1.2 PDF
is based on quoted printable encoding.
If the receiving system is not capable of understanding the "quoted
printable" encoding, it may cause problems.
WORKAROUND
If the customer system is incapable of handling "quoted printable"
encoding, use only version 1.1 PDF files. Another possible solution is to
compress the files before sending them with a third-party compression
utility such as Winzip.
