[Andy Harlan]

Trying to send out via internet mail. Exchange for local
mail. When sending attachments I get error saying
recipient name not recognized MTS-IS Exchange....When
sending regulare mail it works fine. When sending
attachments via Outlook 2000 it works fine. Any ideas?

Not sure if it relates to your problem, but note that using Exchange &
Internet mail in the same profile in Outlook 2000 and prior versions is not
supported and can lead to all kinds of annoyances. Your Outlook is trying to
send Internet out via Exchange, it sounds like....what's your default mail
service?You can upgrade to OL2002/2003 and it will handle multiple account
types much more easily....or have Exchange handle all your mail, or set up
separate profiles, or use OE for Internet mail, etc....
