I have a Samsung Focus and email is configured to an Exchange 2007 server, SP2 with Rollup3.
The email comes in and when I click on the email attachment it says downloading at the top of the screen for a short second, then stops. The paperclip icon includes a down arrow, but it never goes beyond that. If I click the attachment again, it in effect cancels the download. Similar steps with Google gmail, and google works perfectly.
Could this be some bug, or policy with exchange?
