problem with rules and alerts in outlook 2007

I have a problem with incoming mail being moved to specific folders. It alwasy leaves a copy on the original folder.

I set several rules for incoming mail to move it to specific folders. Here is what I did:

Apply ths rule after the message arrived
from xxxxxxx RemoveThis @xxxxxxx.net
and on this machine only
move it ot the XXX folder.

The messages is moved to this folder but a copy is left on the original account. I tried several setting but no luck.

Can anybody help ??

Thanks
