I send a .pdf file and the recipient gets a bat file that cannot be opened.
not all recipients have this problem
..bat or .dat? If it gets changed from .pdf to .bat then something on
the recipient's end is doing that. If you meant they get a .dat
attachment then it is because you are incorrectly using RTF (Rich-Text
Format) in Outlook. Actually HTML is also a RTF format but, for
Microsoft, RTF refers to their proprietary TNEF format. This attaches a
winmail.dat file that contains the formatting information.
Only use RTF in Outlook if you can guarantee that the recipient also
uses Outlook as their e-mail client (and if both sender and recipient
are within the same Exchange organization, like both are employees at
the same company, to prevent mangling of the RTF formatting during
transport). The only e-mail client that understands Microsoft's RTF is
Outlook. Not even Microsoft's Outlook Express understands their RTF.

If you cannot guarantee the recipient is using Outlook then do NOT
compose your e-mails using RTF. Use plain text or HTML format.
