Go to Active-Sync options. High-light INBOX and choose SETTINGS.
Make sure the box for "include file attachments" is checked.

I don't think this will work for the attachments for existing emails, but should work for new ones.

If you have a program you want to "upgrade" just delete it from the Axim inbox, re-sync, then open Outlook and drag the email from the Deleted folder back into the Inbox. Then re-sync again with the Axim. The attachment should work now.

If your talking Outlook.

I was under the impression that the spambots were also capable of scanning the content of newsgroup postings and emails, not just the headers, for email addresses so some clients take caution. Was I wrong? I usually am.
