can receive e/mails but cannot redirect or send from address book.

Are you using Outlook Express? Did this just start, or has the account never worked? If you open a new message window and enter your address, (not send from address book), does that make a difference?If OE and it just started happening, eliminate e-mail scanning.Turn off e-mail scanning in your anti-virus program. It is a redundant layer of protection that eats up CPUs, slows down sending and receiving, and causes a multitude of problems such as time-outs, account setting changes and has even been responsible for loss of messages. Your up-to-date A/V program will continue to protect you sufficiently.
