  • .zip
  • .txt
  • .html
  • Adobe Acrobat (.pdf)
  • WordPerfect (.wpd)
  • Microsoft Word (.doc/.docx)
  • Microsoft Excel (.xls/.xlsx)

The maximum total message size (original mail message and attachment) for the BlackBerry Internet Service is 11MB.  For BlackBerry running BlackBerry 7, attachments up to 8MB in size may be downloaded.  However, the maximum attachment size may be decreased based on the size of the original mail message.  For example, a 3MB email message and 9 MB attachment would exceed the 11MB limit and result in a message truncated due to size.  For BlackBerry smartphones running BlackBerry 6 or earlier, each attachment up to 3MB can be downloaded.
