I sent a mail from Outlook containing an ASCII file attachment. When using TElMessage.ParseMessage on this message (after retrieving it from POP3) and then TElMessage.SaveDatatToFile on the body-part containing the attachment the file saved is in Unicode. (In my case 44 bytes large instead of the original 22 bytes). If I save the same attachment from outlook the file is the correct 22 bytes. Any ideas on why this is?

Why you think that 44 bytes is "incorrect"? Did you look inside the saved file?

Because the original file is 22 bytes in ASCII encoding. The resulting file is 44 bytes and in Unicode encoding. So the files are not equal, the encoding has changed.

Most likely the attachment was loaded as text and parsed. This could happen due to malform attachment headers (eg. content-disposition: inline).

Please post some sample code that shows how you load the message and the message itself to HelpDesk for investigation.
