I had kind of the same problem. I am using Outlook 2003, and i couldn't open any attachments on my BB 7100i. So, i searched around on here and saw a number of times when people said to try using GMail. Google Mail. Sent them that way, and no problems. Just click the message, then scroll down to Open Attachements, click. Then, expand, retrieve. should be good to go. Hope this helps.
