Recently I have been unable to send emails in Outlook. I can receive
with no problems. But for email in my Outbox I get
'Sending and receiving reported error (0x8004210B): The operation timed
out waiting for a response from the sending (SMTP) server.'
I have 4 accounts and all generate this error.

Are you using a POP or IMAP mail server and not an Exchange server?
This really sounds like it's just issues with your email server. I
certainly see them from my home ISP's SMTP server.
