Email address problem

Installed a new HP system with windows 7, all seems to have gone well. I have 2 problems with email addresses.

1. A known good address gives a unable to deliver message when using windows live address book. This is the only address with this problem, all others work. This address worked with old system. I can open my local ISP's web mail and us it and it works as expected.

2. Yahoo address book appears to work as advertised until you select "insert addresses "; at that time the address window goes blank and appears to be searching/attempting a process.

Thanks;

I have checked the address several times; deleted and re-entered it manually several times. I have also entered it automatically from emails to no avail.

any suggestions asto why the yahoo address book hangs up?

My mail client is windows 7/live.com.

The failure message is:

This is an automatically generated delivery status notification.
Delivery to the following recipients failed.

mprall#directcon.net

Admin: I changed @ to # to prevent harvesting


Directcon is a local ISP. I half a dozen or so address that I send to frequently with them with no problems; just this address. I can send email with Yahoo and with Directcons web mail server to this address.

I believe I have a corrupted address in my Yahoo address book; I will call it a solved problem at the moment.
