Q. Our company just upgraded our Microsoft Exchange server and I can no longer send attachments. If I attach a jpeg it arrives as zero K in size unless I sending in a zip file. Is there a workaround?
A. The Internet deals best with ASCII text files. However many of the files we deal with regularly are also binary files. When a binary file is transferred on the Internet via an email program or via FTP transfer , the file may become corrupt. As a result the files should be â€œencodedâ€ into a text format before they are transferred.
When you create a â€œzipâ€ archive or use stuffit â€œ.sitâ€ or Appleâ€™s disk image â€œ.dmgâ€ you are in fact storing the file into a format that will survive transfer on the Internet. When you attach a file in an email client it will normally encode the files based on a default set up.
I recommend that all users of Microsoft email clients set the default attachments to â€œWindows base64/MIMEâ€ format. Apple Mail users can choose â€œWindows Friendly Attachmentsâ€. This is an encoding that all Windows machines understand. Windows computers comprise about 80% of all computers so conforming doesnâ€™t affect Mac users that much. In the case of the Exchange Server the base64 formatted files will remain intact.
