Cancel.
2. On the Tools menu, click Accounts.
3. On the Mail tab, click MSN
Mail, and then click Properties.
NOTE: The name of your MSN

not contain any spaces.

that the e-mail address specified on the To: line is typed in the
correct
format. Make sure there are no spaces or extra or missing periods in

and
then click OK.
