Windows 7 Outlook mail can't mail attachment to XP Outlook Express

[Steve12233]

I attach something to my Windows seven Outlook mail and send it to my home XP-Outlook Express compuyer. The email goes through, but without the attachment.

ALSO: When I receive an email and want to reply, it never has the original email on the reply "page." How come. Is there a setting for this?

Many thanks,

Steve
